Overview

The Web User Interface (WUI) allows you to set up, modify, and view router configuration variables and operational data.

  1. If the ADSL router is not on, turn on the power. Wait about one minute.

  2. In a Web browser on the PC, connect to http://192.168.1.1/ to enter the router's configuration program. The browser should connect and you should see the Enter Network Password screen shown below.

Type admin in the User Name and Password fields, and click OK. These values can be changed later in the Web User Interface (WUI).

 

Restoring Factory Default Settings

It is only necessary to restore the router to the factory default settings when the router is in a non-functioning state or you wish to reprogram completely. In the majority of cases, your router is already configured to the default values. The factory default configuration can be restored either by pushing the reset button for more than five seconds, or by clicking the Restore Default Configuration option in the Restore Settings screen.

The following default settings are present when setting up the router for the first time.

  • LAN port IP address: 192.168.1.1
  • WAN connection type: bridging
  • WAN ATM PVC encapsulation: LLC
  • Local administrator account name: admin
  • Local administrator account password: admin
  • Local non-administrator account name: user
  • Local non-administrator account password: user
  • Remote WAN access: disabled
  • Remote WAN access account name: support
  • Remote WAN access account password: support
  • NAT and Firewall: disabled
  • DHCP server on LAN interface: enabled
  • WAN IP address: none

Begin Quick Setup

Begin Quick Setup allows the user to configure the ADSL router for DSL connectivity and Internet access. It also guides the user through the ISP network setup first and then the home or office network setup. The USRobotics SureConnect ADSL 4-Port Router supports the following five ISP network operating modes over router ADSL interface:

  • PPP over Ethernet (PPPoE)
  • PPP over ATM (PPPoA)
  • MAC Encapsulated Routing (MER)
  • IP over ATM (IPoA)
  • Bridging

The ISP network operating mode operation depends on the service provider's configuration on the Central Office side and Broadband Access Server (BRAS) for your ADSL line.

Your ISP should be able to provide the following, if needed:

  • VPI/VCI values
  • ADSL Standard (Modulation)
  • Encapsulation Mode
  • Authentication (PAP or CHAP) for PPP connections

The following configuration considerations apply:

  • If the service provider provides PPPoE service, then the connection selection depends on whether the LAN-side device (typically a PC) is running a PPPoE client or whether the 4-Port Router is to run the PPPoE client. The 4-Port Router ADSL router can support both cases simultaneously. Consult your ISP instructions on the appropriate protocol to use.
  • NAPT and Firewall are always enabled when PPPoE or PPPoA mode is selected, but they can be enabled or disabled by the user when MER or IPoA mode is selected. NAPT and Firewall are always disabled when Bridge mode is selected.
  • Depending on the network operating mode, and whether NAPT and Firewall are enabled or disabled, the main panel will display or hide the NAPT/Firewall menu. For instance, at initial setup, the default network operating mode is Bridge. The main panel will not show the NAPT and Firewall menu.
  1. Click Begin Quick Setup to start the setup process.
  2. Enter the appropriate VPI and VCI and click Next. The valid VPI range is from 0 to 255. The valid VCI range is from 32 to 65535.

Connection Type

The Connection Type screen allows you to select the type of network protocol over the ATM PVC supported by the Internet Service Provider. Refer to the beginning of this section for a bridge description of these protocols.

Select the protocol as assigned by your ISP and proceed to the matching sections in this manual for further instructions.

 

PPP over ATM (PPPoA) / PPP over Ethernet (PPPoE)

  1. Select the PPP over ATM (PPPoA) or PPP over Ethernet (PPPoE) radio button and click Next.
  2. Select the appropriate Encapsulation Mode. The following screen appears:
  3. The screen provides fields to enter the PPP Username and the PPP Password. The password requirement is dependent on the particular requirements of the ISP or the ADSL service provider.

    The WUI allows a maximum of 256 characters in the PPP user name and a maximum of 32 characters in PPP password.

    The 4-Port Router can be configured to disconnect if there is no activity for a specific period of time by selecting the Disconnect if no activity check box.

    The entered value must be between 1 minute to 4320 minutes. Default is 30 minutes. The PPP IP Extension is a special feature deployed by some service providers. Unless your service provider specifically requires this setup, do not select it.

    The PPP IP Extension supports the following conditions:

    • Allows only one PC on the LAN
    • The public IP address assigned by the remote using the PPP/IPCP protocol is actually not used on the WAN PPP interface. Instead, it is forwarded to the PC's LAN interface through DHCP. Only one PC on the LAN can be connected to the remote since the DHCP server within the ADSL router has only a single IP address to assign to a LAN device.
    • NAPT and firewall are disabled when this option is selected.
    • The ADSL router becomes the default gateway and DNS server to the PC through DHCP using the LAN interface IP address.
    • The ADSL router extends the IP subnet at the remote service provider to the LAN PC. That is, the PC becomes a host belonging to the same IP subnet.
    • The ADSL router bridges the IP packets between WAN and LAN ports, unless the packet is addressed to the router's LAN IP address.
  4. After entering your settings, click Next. The following screen appears:
  5. This page allows the user to configure the LAN interface IP address, subnetmask and DHCP server, if the user would like this ADSL router to assign dynamic IP addresses, DNS server and default gateways to other LAN devices. Select the button Enable DHCP server on the LAN to enter the starting IP address and end IP address and DHCP lease time. Click Next after completion. The following screen appears:
  6. The Network Setup - Summary Screen presents the entire configuration summary. Click Finish if the settings are correct.

After clicking Finish, the router will save the configuration to delete memory and reboot. The WUI will not respond until the system is brought up again. After the system is up, close the Web browser and relaunch another Web browser session.

 

MAC Encapsulated Routing (MER)

To configure MER, do the following:

  1. Select the MAC Encapsulated Routing (MER) radio button.
  2. Select the appropriate Encapsulation Mode and click Next. The following screen appears:
  3. The values that must be entered in the fields should be provided by the ISP.

  4. If IP addressing can be obtained automatically through the DHCP client in the ADSL router, select Obtain an IP address automatically; otherwise, the user must enter the WAN interface IP address, subnet mask, and default gateway address.
  5. If DNS server addresses can be obtained automatically through the DHCP, select Obtain DNS server address automatically; otherwise, the user must enter the preferred DNS server address and the optional alternative DNS server address and click Next. The following screen appears:

    • Enable NAT checkbox: If the LAN is configured with a private IP address, the user should select this checkbox. If a private IP address is not used on the LAN side, this checkbox should be deselected.
    • Enable Firewall checkbox: If the firewall checkbox is selected, the user can configure firewall features after the system comes up from the reboot. If firewall is not used, this checkbox should be de-selected.
  6. Assuming you prefer to use both the Enable NAT and Enable Firewall settings, click Next.
  7. To use the DHCP service on the LAN, select the Enable DHCP server on the LAN check box and enter the Start IP address, the End IP address, and DHCP lease time. This configures the router to automatically assign IP addresses, default gateway address, and DNS server addresses to each of your PCs.


  8. After completion, click Next.
  9. The Network Setup - Summary Screen presents the entire configuration summary. Click Finish to complete the configuration (which requires about 1 minute to complete) or Back to change any of the settings.

When the configuration is completed and the unit has rebooted, the 4-Port Router is ready for operation and the LEDs display as described in the LED description tables.

 

IP over ATM (IPoA)

To configure IP over ATM (IPoA), do the following.

  1. Select the IP over ATM (IPoA) radio button.
  2. Select the appropriate Encapsulation Mode and click Next.

Notice that DHCP client is not supported over IPoA. The user must enter the WAN interface IP address, the remote end IP address for the default gateway setup, and the DNS server addresses provided by the ISP and click Next. The following screen appears:

  • Enable NAT checkbox: If the LAN is configured with a private IP address, the user should select this checkbox. If a private IP address is not used on the LAN side, this checkbox should be deselected to free up system resources for better performance.
  • Enable Firewall checkbox: If the firewall checkbox is selected, the user can configure firewall features after the system comes up from the reboot. If firewall is not used, this checkbox should be de-selected to free up system resources for better performance.

Assuming you prefer to use both the Enable NAT and Enable Firewall settings, click Next. The following screen appears.

 

  1. To use the DHCP service on the LAN, select the Enable DHCP server on the LAN check box and enter the Start IP address, the End IP address, and the DHCP lease time. This configures the router to automatically assign IP addresses, default gateway address, and DNS server addresses to each of your PCs.


  2. After completion, click Next. The following screen appears:
  3. The Network Setup - Summary Screen presents the entire configuration summary. Click Finish to complete the configuration (which requires about 1 minute to complete) or Back to change any of the settings.

Bridging

Select the bridge operating mode if it is instructed by your ADSL service provider.

To configure Bridging, do the following:

  1. Select the Bridging radio button and click Next.
  2. Select the appropriate Encapsulation Mode and click Next. The following screen appears:
  3. Deselect Enable Bridge Service to disable ISP traffic on this service and click Next.
  4. Enter the IP address for the LAN interface. The default IP address is 192.168.1.1. The LAN IP interface in bridge operating mode is needed for local users to manage the ADSL router.



    Notice that there is no IP address for the WAN interface in bridge mode, and the remote technical support user cannot access the ADSL router. Click Next.
  5. The Network Setup - Summary Screen presents the entire configuration summary. Click Finish to complete the configuration (which requires about 1 minute to complete) or Back to change any of the settings.

After having completed the Quick Setup, you should be able to browse the Internet and no additional configuration is needed.

Service Provider Settings

The DSL Settings dialog box allows you to select an appropriate modulation mode.

Option Description
Auto Mode (G.Dmt, G.lite or T1.413) Sets the system auto-sense between G.Dmt, G.lite, or T1.413.
G.Dmt/G.lite Sets G.Dmt/G.lite if you want the system to use either G.Dmt or G.lite mode.
T1.413 Sets the T1.413 if you want the system to use only T1.413 mode.
G.Dmt Sets the system to use only G.Dmt mode.
G.lite Sets the system to use only G.lite mode.

In most cases, automode will suffice and should only be changed at the request of your ISP.

ADSL Standard Settings

This release supports ADSL2 connection. Check with your ISP to make use of this higher rate connection standad.

The DSL Advanced Settings dialog box allows you to select an appropriate test mode.

Warning!! These tones are for your ISP to perform DSL line testing. Running these tests may render your DSL service inoperable.

Option Description
Normal Normal mode of operation.
Reverb Send Reverb signal only.
Medley Send Medley signal only.
No retrain Stay in showtime even after the modem is disconnected.

All three of these modes enable PSD measurements for each phase of training and showtime.

 

Tone Selection

The Tone Selection button prompts the ADSL Tone Settings dialog box. This allows you to select an appropriate number of upstream and downstream tones. Click Apply after you have made your selections.

 

WAN Setup

The WAN Setup dialog box allows you to Edit or Remove your ISP configuration that was configured either by EasyConfigurator or during the Quick Setup step. Changes will take effect only after you choose Finish and reboot your router.

 

Access Control - Services

Select Services under the Access Control section. This screen allows for the control of device management to specify protocol for the LAN and WAN sides.

Access Control - IP Addresses

Select IP Addresses under the Access Control section. Select Disable or Enable here to either activate or deactivate the Access Control Mode (Device Management) by user's IP address. To add an IP Address to the list select Add. To remove an IP Address from the list, select Remove.

 

Access Control - Passwords

Select Passwords under the Access Control section. Use this screen to change or create Device Management passwords. When complete, click Apply.

Quality of Service

The Quality of Service (QoS) tab is useful only when all of the following conditions are met:

  • PVC is not in bridge mode (that is, the WAN protocol can be in PPPoA, PPPoE, IPoA or MER)
  • PVC is in set to one of the following ATM service categories:
    - UBR-with-PCR
    - UBR-without-PCR
    - non-realtime-VBR
  • There are enough ATM TX queues left in the system.

IP QoS is executed in the IP layer. It will classify traffic according to the classification rules. Each rule may contain a combination of the following conditions: protocol (TCP/UDP/ICMP), source IP address/subnet mask, destination IP address/subnet mask, source port (one or range), destination port (one or range). The result of matching a classification rule will produce a priority (high, medium, low) and a type of service (don’t care, Normal Service, Minimum Cost, Maximum Reliability, Maximum Throughput, Minimum Delay).

The IP Type of Service (TOS) of the matching rule will overwrite the original IP header TOS field if “don’t care” is not selected.

The priority of the matching rule determines which ATM TX queue to send over the PVC if the packet is routed to this PVC. The ATM SAR scheduler transmits the packet according to the following order:

  1. ATM service categorizes from the highest to lowest order: CBR, rt-VBR, rrt-VBR, UBR
  2. For the same service category: Priority level from high, medium, to low
  3. For the same priority level: round robin.

IP QoS will only take effect if the packet is routed to a QoS-enabled PVC. If it is routed to a regular QoS-disabled PVC, it will be transmitted at the same priority level as the low priority of a QoS enabled PVC of the same ATM service category.

 

Network

LAN Setup/DHCP Server

Configure the DSL Router IP Management Address and Subnet Mask for LAN interface and DHCP Server.

 

Default Gateway

The Default Gateway Configuration dialog box allows you to configure a static default gateway IP address.

If deselecting the Enable Automatic Assigned Default Gateway checkbox, the following screen appears:

If you are configuring your router for either Routed Mode or Static MER Mode, you should enter a static Default Gateway IP Address in the corresponding field and use the appropriate WAN interface.

It is significant that both of these fields are compatible with each other. The WAN interface check box should report the same value as found in the Service Name field box on the WAN Setup screen.

These settings will take affect only after you click Apply. If changing the Automatic Assigned Default Gateway from deselected to selected, you must reboot the router to get the automatically assigned default gateway.

 

DNS Server Configuration

The DNS Server Configuration dialog box allows you to configure a static DNS server IP Address.

If deselecting the Enable Automatic Assigned DNS check box, the following screen appears:

  • If you are configuring your router for either Routed Mode or Static MER Mode, you should enter a static DNS server IP Address in the Primary DNS Server field. A secondary DNS server could also be entered.
  • These settings will take affect only after you click Apply. If changing the Automatic Assigned DNS from deselected to selected, you must reboot the router to get the automatically assigned DNS address.

Dynamic DNS

DNS (Domain Name Service) is responsible for resolving an Internet name such as www.usr.com into an IP address for your ISP's equipment to find and serve you with it's Web contents. If we reverse the process, you use a Dynamic DNS Service. By registering with these Dynamic DNS Service providers, and programing your router, you router's public address will be resolved.

 

Routing

The Routing dialog box allows you to configure Static Route entry and static ARP entry.

Pressing Add will open the following screen:

Routing Static Route Add

Pressing Add will open the following screen and you can add static routes

  1. Fill in data for:
    • Destination Network Address and Subnet Mask
    • Gateway IP Address
  2. Select the interface for which your settings apply
  3. Click Apply.

 

Routing ARP

The MAC address has the following format "xx:xx:xx:xx:xx:xx" where xx are hexidecimal numbers.

 

Security

Firewall

Firewalls use one or more of three methods to control traffic flowing in and out of the network:

  • Packet filtering: Packets (small chunks of data) are analyzed against a set of filters. Packets that make it through the filters are sent to the requesting system, and all others are discarded.
  • Proxy service: Information from the Internet is retrieved by the firewall and then sent to the requesting system and vice versa.
  • Stateful inspection: A newer method that doesn't examine the contents of each packet but instead compares certain key parts of the packet to a database of trusted information. Information traveling from inside the firewall to the outside is monitored for specific defining characteristics, then incoming information is compared to these characteristics. If the comparison yields a reasonable match, the information is allowed through. Otherwise, it is discarded.

IP Filtering-Outbound Filters

The firewall blocks internal users from accessing the Internet. There are two ways to accomplish this:

Using the TCP/UDP port to block internal users from accessing the Internet (also known as Port Filtering).

Using the IP address to block a specific user from accessing the Internet (also known as Address Filtering). The Firewall dialog box allows you to configure outgoing packet types to be sent using either TCP or UDP (or a combination of both) from specific ports.

The following screen appears after you click Add.

Firewall Outgoing - Port Filter Screen Fields

Destination Subnet Mask:

Enter the subnet mask for the destination IP address.

Destination Port (port or port:port)

Enter the destination port number, or range of port numbers, you want to allow access (for destination IP).

 

Network Address and Port Translation (NAPT)

Network Address and Port Translation (NAPT) allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network. This means that only a single, unique IP address is required to represent an entire group of computers.

Implementing dynamic NAPT automatically creates a firewall between your internal network and outside networks, or between your internal network and the Internet. NAPT only allows connections that originate inside the sub-domain. Essentially, this means that a computer on an external network cannot connect to your computer unless your computer has initiated the contact. You can browse the Internet and connect to a site, and even download a file; but somebody else cannot latch onto your IP address and use it to connect to a port on your computer.

Under the NAPT environment, all computers behind the NAPT are not accessible from outside (i.e., the WAN). However, if public services, such as web servers, ftp servers or e-mail servers, are needed from your private network, a virtual server can be configured to set up permit secured access. A virtual server setup enables a connection from outside to be redirected to a host running the services on the private subnet. This host running the services is called a virtual server (a virtual server is synonymous with IP forwarding).

The NAPT dialog box allows you to configure Virtual Servers and DMZ Host settings by adding, removing, and saving.

 

Virtual Servers

Selecting the Add button prompts the following screen:

Option Description
Service Name Allows the selection of an existing service from a drop-down-menu (web, FTP, e-mail).
Custom Server Allows for an entry of a customer service where the name is known, but not listed in the Select a Service drop-down.
Server IP Address The IP address of your computer that functions as a server.
Protocol Allows the selection of a transport protocol (UDP, TCP, or both).
External Port (start/end) Allows the entry of an individual external port or range of ports.
Internal Port (start/end) Allows the entry of an individual internal port or range of ports.
Internal server IP address The IP address of your computer that functions as a server.

 

Port Triggering (also known as Port Forwarding)

Enter the application name, outgoing protocol, outgoing port range, incoming protocol, incoming port range, and click Apply to forward IP packets for this application to the specified ports.

A port trigger is available to a single active session and can not support multiple triggers to multiple outgoing clients.

 

DMZ Host

The DeMilitarized Zone (DMZ) Host option is used to forward IP packets from the WAN that do not belong to any of the applications configured in the virtual servers table, to the DMZ host computer. While virtual server can only forward (redirect) a limited number of services (ports), DMZ hosting allows all the services (ports) running on the DMZ host, to be accessible externally.

Selecting the DMZ Host button prompts the following screen.

To configure the DMZ, type in the address of your computer that will function as a DMZ Host.

UPNP

By default, UPNP is enabled. To disable, deselect Enable UPNP and click Apply.

 

Tools

Upgrade Gateway

The Update Software screen allows you to obtain an updated software image file from your ISP. Manual software upgrades from a locally stored file can be performed using the following screen.

  1. Select the new image file after clicking Browse.
  2. Click Update Software. Completion of this step takes about two minutes. The 4-Port Router will reboot in the process.

Restore to Defaults

The original factory installed settings can be restored by clicking the Restore Default Configuration option in the Restore Settings screen.

This entry has the same effect as the hardware reset-to-default button. The 4-Port Router hardware and the boot loader software supports the "reset to default" button. If the reset button is continuously pushed for more than 5 seconds, the boot loader will erase all the configuration data saved in the "Permanent Storage" section on the flash memory.

If you hold the switch for more than 30 seconds, the router boots into recovery mode. Simply power cycle to go back to normal boot mode.

Default Settings

The 4-Port Router default settings are:

  • Default network operating mode is Bridging.
  • Default LAN port IP address is 192.168.1.1, subnet mask is 255.255.255.0
  • Local User Name: admin
  • Local User Password: admin
  • Remote User Name: support
  • Remote User Password: support

After the Restore Default Configuration button is selected, the following screen appears.

Configuration - Backup

To save your DSL Gateway configuration settings, click Backup Configuration and select a folder on your hard drive.

Note: You must have Explorer 6.0 or greater to successfully save your configuration settings.

Configuration - Update

To update your DSL Gateway configuration settings, follow the steps provided on the screen.

Note: You must have Explorer 6.0 or greater to successfully update your configuration settings.

Reboot Gateway

The Reboot Gateway dialog box allows you to reboot the gateway. The reboot takes two minutes.

Diagnostics

The Diagnostics menu provides feedback on the connection status of the Wireless Gateway and the ADSL link. A description of each test can be obtained by clicking the Help button associated with the test.

Without an active ADSL connection, many of the tests will not be activated, as shown in the following screen.

When the current network operating mode is in bridge, the default gateway and DNS server tests will not be activated.

Rerunning Diagnostics Tests

There are two buttons at the bottom of the screen:

  • Rerun Diagnostic Tests
  • Rerun Diagnostic Tests With OAM F4

When either of the Rerun Diagnostic Tests buttons are clicked, all the diagnostic tests are repeated. Normally, if one or more tests return a failure status, the user should rerun all the tests again to more thoroughly diagnose the problems encountered.

When you click Rerun Diagnostic Tests With OAM F4, ATM OAM F4 loopback cells are also transmitted, in addition to OAM F5 cells. It is possible that the ATM OAM F4 loopback or segment tests may not be supported by the ATM devices in the DSL service provider's network. For this reason, the OAM F4 test is separated from the general diagnostics tests. When an OAM F4 failure is encountered, the output screen will appear as an F4 Fail. The graphic below shows an example of diagnostics results when the PVC is configured in the PPPoE operating mode.

Diagnostic Test Description

Test Description
Ethernet Connection
  • Pass: Indicates that the Ethernet interface from your computer is connected to the LAN port of your DSL gateway. A flashing or solid green LAN LED on the gateway also signifies that an Ethernet connection is present and that this test is successful.
  • Fail: Indicates that the DSL gateway does not detect the Ethernet interface on your computer.
ADSL Synchronization
  • Pass: Indicates that the DSL modem has detected a DSL signal from the telephone company. A solid DSL LED on the modem also indicates the detection of a DSL signal from the telephone company.
  • Fail: Indicates that the DSL modem does not detect a signal from the telephone company's DSL network. The DSL LED will continue to flash green.
ATM OAM Segment Ping

The modem transmits OAM F4/F5 (if you rerun the test with OAM F4, both F4 and F5 are sent, otherwise only F5 is sent) segment loopback requests and expects a reply within 5 seconds. This test verifies that ATM continuity exists between the virtual channel link segment from the modem to the DSL provider network (typically this is a DSLAM at the DSL provider site).

  • Pass: Indicates that the DSL modem can communicate with the DSL provider network.
  • Fail: Indicates that the DSL modem may not be able to communicate with the DSL provider network. This test may have an effect on your Internet connection. Occasionally the DSL provider network may intentionally block this traffic. Therefore, if this test fails, but you are still able to access the Internet, there is no need to troubleshoot this issue.
ATM OAM End-to-end Ping

The modem transmits OAM F4/F5 (if you rerun the test with OAM F4, both F4 and F5 are sent, otherwise only F5 is sent) end to end loopback requests and expects a reply within 5 seconds. This test verifies ATM connectivity of the virtual channel link with the ATM PVC endpoint, such as a remote broadband access router located at the DSL provider or ISP site.

  • Pass: Indicates that the DSL modem can communicate with the DSL provider network.
  • Fail: Indicates that the DSL modem may not be able to communicate with the DSL provider network. Occasionally the DSL network provider may intentionally block this traffic. Therefore, if this test fails but you are still able to access the Internet, there is no need to troubleshoot this issue.
PPP server

For PPPoA operating mode, the modem checks if PPP (LCP and IPCP) is connected to the remote PPP server. For PPPoE operating mode, this test verifies that the modem can detect a PPPoE server by checking if it can receive a PADO (PPPoE Active Discovery Offer) packet from a PPPoE server after sending a PADI (PPPoE Active Discovery Initiation) broadcast packet.

  • Pass: Indicates that the DSL modem has discovered a PPPoE server or can connect to a PPPoA server.
  • Fail: Indicates that the DSL modem failed to discover a PPPoE server or connect to a PPPoA server.
  • A flashing green WAN IP on the modem signifies an attempt to establish a PPP connection.
Authentication with ISP

Verifies that the provided PPP username and password stored in the DSL modem have been authenticated by the PPP server within the ISP network.

  • Pass: Indicates that your username and password stored in the DSL modem has authenticated with the ISP's network.
  • Fail: Indicates that the PPP username and password were rejected by the PPP server at the ISP site. Either the PPP user name or password were configured incorrectly, or the user account has not been properly established at the ISP. The user should re-enter the PPP user name and password and retry. If a failure condition persists, contact the ISP support.
Assigned IP address

Verifies that the DSL modem has a valid IP address (here, a PPP WAN IP address) from the PPP server.

  • Pass: Indicates that the DSL modem has a valid IP address from the PPP server.
  • Fail: Indicates that the DSL modem does not have a valid IP address from the PPP server.
Ping default gateway
  • Pass: Indicates that the DSL modem can communicate with the initial network entry point. This is usually the IP address of the ISP router.
  • Fail: Indicates that the DSL modem was unable to communicate with the initial network entry point.
Ping Primary Domain Name Server

Verifies that the DSL modem can communicate with the primary domain name server (DNS).

  • Pass: Indicates that the DSL modem can communicate with the primary DNS.
  • Fail: Indicates that the DSL modem was unable to communicate with the primary DNS.

 

SNMP - Configuration

You can help your ISP troubleshoot the router by enabling this feature upon request from your ISP. It allows a management application to retrieve statistics and status from the SNMP agent in this device. If you enable this feature, you do not need to enable Remote Access for a management application to retrieve statistics and status from the router. The information entered in this screen should correspond with the information set in the management application.

System Log

The System Log screen allows you to view the system events log or to configure the System Log options.

The System Log feature allows you to enable or disable System Log options.

  1. Click Configure System Log to display the following screen:
  2. Select from the desired System Log options, enter an option, then click Apply.
  3. System Log - Configuration Options

    Option Description
    Log Status Log Status indicates whether the system is currently recording events. The user can enable or disable event logging. By default, it is disabled. To enable it, click Enable and then Apply.
    Log Level

    Log Level allows you to configure the event level and filter out unwanted events below this level. The events ranging from the highest critical level "Emergency" down to this configured level will be recorded to the log buffer on the Wireless Gateway SDRAM. When the log buffer is full, the newer event will wrap up to the top of the log buffer and overwrite the old event. By default, the log level is "Debugging," which is the lowest critical level. The following log levels are:

    • Emergency = system is unusable
    • Alert = action must be taken immediately
    • Critical = critical conditions
    • Error = error conditions
    • Warning = warning conditions
    • Notice = normal but significant conditions
    • Informational = information events
    • Debugging = debug-level messages

    Emergency is the most serious event level, whereas Debugging is the least important. For instance, if the log level is set to Debugging, all the events from the lowest Debugging level to the most critical level Emergency level will be recorded. If the log level is set to Error, only Error and the level above will be logged.

    Display Level Display Level allows the user to select the logged events and display on the "View System Log" page for events of this level and above to the highest Emergency level.
    Mode Mode allows you to specify whether events should be stored in the local memory or be sent to a remote syslog server, or both simultaneously. If "remote" mode is selected, view system log will not be able to display events saved in the remote syslog server. There are several types of syslog server software available for Windows and Linux operation systems. A free syslog server for Windows is Kiwi Syslog Daemon which can be obtained from www.kiwisyslog.com. When either Remote mode or Both mode is configured, the WUI will prompt the user to enter the Server IP address and Server UDP port.
    Server IP Address Field that appears when Remote or Both is selected in the Mode field.
    Server UDP Port Field that appears when Remote or Both is selected in the Mode field. Prompts the user to enter UDP port number of the SysLog server. A well known UDP port number, 514, is normally assigned to syslog. However, the user can overwrite with another UDP port number if a different UDP port is used by that particular syslog server.
