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:
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:
The following configuration considerations apply:
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.
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:
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.
To configure MER, do the following:
The values that must be entered in the fields should be provided by the ISP.
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:
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.
To configure IP over ATM (IPoA), do the following.
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:
Assuming you prefer to use both the Enable NAT and Enable Firewall settings, click Next. The following screen appears.
Select the bridge operating mode if it is instructed by your ADSL service provider.
To configure Bridging, do the following:
After having completed the Quick Setup, you should be able to browse the Internet and no additional configuration is needed.
The DSL Settings dialog box allows you to select an appropriate modulation mode.
|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.|
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.
|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.
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.
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.
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.
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.
Select Passwords under the Access Control section. Use this screen to change or create Device Management passwords. When complete, click Apply.
The Quality of Service (QoS) tab is useful only when all of the following conditions are met:
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:
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.
Configure the DSL Router IP Management Address and Subnet Mask for LAN interface and DHCP Server.
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.
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.
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:
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.
The Routing dialog box allows you to configure Static Route entry and static ARP entry.
Pressing Add will open the following screen:
Pressing Add will open the following screen and you can add static routes
The MAC address has the following format "xx:xx:xx:xx:xx:xx" where xx are hexidecimal numbers.
Firewalls use one or more of three methods to control traffic flowing in and out of the network:
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
Selects TCP, UDP, or a combination of TCP/UDP.
Source IP address (LAN)
Enter the IP address you do not want to have access to the destination IP.
Source Port (LAN)
Enter the source port number, or range of ports, you want to block access (for source IP).
Destination IP address
Enter the IP address you do not want the source IP address to have access to.
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 block access (for destination IP).
The screen allows inbound IP addresses to reach your computer. To add an IP address to the inbound filter list, click Add. To remove an IP address from the inbound filter list, click Remove.
IP Filtering - Inbound Filters
Selects TCP, UDP, or a combination of TCP/UDP.
Source IP address (WAN)
Enter the IP address you want to have access to the destination IP.
Source Port (WAN)
Enter the source port number, or range of ports, you do not want to block access (for source IP).
Destination IP address (LAN)
Enter the IP address you want the source IP address to have access to.
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) 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.
Selecting the Add button prompts the following screen:
|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.|
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.
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.
By default, UPNP is enabled. To disable, deselect Enable UPNP and click Apply.
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.
Restore to Defaults
The original factory installed settings can be restored by clicking the Restore Default Configuration option in the Restore Settings screen.
The 4-Port Router default settings are:
After the Restore Default Configuration button is selected, the following screen appears.
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.
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.
The Reboot Gateway dialog box allows you to reboot the gateway. The reboot takes two minutes.
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.
There are two buttons at the bottom of the screen:
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
|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).
|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.
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.
|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.
|Assigned IP address||
Verifies that the DSL modem has a valid IP address (here, a PPP WAN IP address) from the PPP server.
|Ping default gateway||
|Ping Primary Domain Name Server||
Verifies that the DSL modem can communicate with the primary domain name server (DNS).
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.
The LAN Statistics screen shows the byte transfer, packet transfer, and error statistics for the Ethernet interface.
The WAN Statistics screen shows the byte transfer, packet transfer, and error statistics for the service settings.

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.
System Log - Configuration Options
|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 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 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.|
