Advanced Setup | System
Configure the system parameters, including time zone, password and remote management.


Advanced Setup | System | Time Zone
Use the section below to configure the U.S. Robotics 802.11g Wireless Router's system time. Select your timezone and configure the daylight savings option based on your location. This information is used for the time/date parental rules you can configure with the U.S. Robotics 802.11g Wireless Router's Advanced Firewall. This information is also used for your network logging.


Advanced Setup | System | Password Settings
Use this menu to restrict management access based on a specific password. By default, password is 'admin'(all lowercase). So please assign a new password to the Administrator as soon as possible, and store it in a safe place.
Passwords can be empty or contain 3-12 printable characters, and are case sensitive.


Advanced Setup | System | Syslog Server
"Syslog is a protocol to transmit the event notification messages across the network. The importance of a syslog message is defined based on its Severity and Facility levels. There are eight severity levels (0-7) and twenty four facility levels(0-23) defined for syslog messages.
Configuration of syslog server includes setting up the server IP address. The address of the syslog server can be received from DHCP server in Auto Mode or can be set manually in Manual Mode."


Advanced Setup | WAN
Wide Area Network. A network that connects computers located in geographically separate areas, (i.e., different buildings, cities, countries). The Internet is a wide area network.


Advanced Setup | WAN | Dynamic IP
The WAN port is connected to a Cable/DSL modem that provides dynamic IP addresses. In this case, the WAN port will automatically obtain an IP address from the DHCP server. The Host Name is optional, but may be required by some Service Provider's. If necessary, you can use the "Release" and "Renew" buttons on the Status page to release and renew the WAN IP address.


Advanced Setup | WAN | PPPoE
The WAN port is connected to an xDSL modem. Many service providers provide PPP over Ethernet (PPPoE) service. The U.S. Robotics 802.11g Wireless Router supports connection on demand and auto-reconnect features for PPPoE service. If the auto-reconnect is checked, the PPP connection will only be initialized when there is a request for Internet access from local clients. After an Idle Timeout, when no Internet traffic is requested, the PPP connection will be torn down automatically.

Enter the PPPoE user name and password assigned by your Service Provider. The Service Name is normally optional, but may be required by some service providers. Enter a maximum Idle Time (in minutes) to define a maximum period of time for which the Internet connection is maintained during inactivity. If the connection is inactive for longer than the Maximum Idle Time, then it will be dropped. You can enable the auto-reconnect option to automatically re-establish the connection as soon as you attempt to access the Internet again.


Advanced Setup | WAN | PPTP
Point-to-Point Tunneling Protocol. A version of PPP (Point-to-Point Protocol) that has the ability to encapsulate packets of data formatted for one network protocol in packets used by another protocol. This tunneling technique allows TCP/IP data to be transmitted over a non-TCP/IP network. PPTP can be used to join different physical networks using the Internet as an intermediary.


Advanced Setup | WAN | Static IP
If your Service Provider has assigned a fixed IP address; enter the assigned IP address, subnet mask and the Gateway address provided by your service provider.


Advanced Setup | WAN | BigPond
The BigPond internet service is available in Australia.


Advanced Setup | WAN | DNS
A Domain Name Server (DNS) is an index of IP addresses and Web addresses. If you type a Web address into your browser, a DNS server will find that name in its index and find the matching IP address. Most ISP's provide a DNS server for speed and convenience. Since your Service Provider may connect to the Internet with dynamic IP settings, it is likely that the DNS server IP's are also provided dynamically. However, if there is a DNS server that you would rather use, you need to specify the IP address here.
The primary DNS will be used first, in the case of the primary DNS access failure, the secondary DNS will be used.


Advanced Setup | LAN
The U.S. Robotics 802.11g Wireless Router supports static IP addresses with a Class C subnet (255.255.255.0). The user can also enable the DHCP server to allow automatic allocation of IP addresses to the LAN client PCs. Note that the network address of the address pool must be the same as the IP address of the device, otherwise an error message will appear and the modification will be denied.


Advanced Setup | Wireless
Configure the wireless SSID, transmission rate, basic rate, channel.
To Check the setting of the parameters such as Beacon Interval, RTS Threshold, Fragmentation Threshold and others.


Advanced Setup | Wireless | Channel and SSID
This page allows you to define SSID, Transmission Rate, Basic Rate and Channel ID for wireless connection. In the wireless environment, this U.S. Robotics 802.11g Wireless Router can be acting as an wireless access point. These parameters are used for the mobile stations to connect to this access point.


Advanced Setup | Wireless | Security
Encryption transmits your data securely over the wireless network. Matching encryption keys must be setup on your U.S. Robotics 802.11g Wireless Router and wireless client devices to use encryption. Do you want to use encryption?


Advanced Setup | Wireless | WDS
With the arrival of the AP-2000 Access Points, WDS operation as defined by the IEEE802.11 standard has been made available. Using WDS it is possible to wirelessly connect Access Points, and in doing so extend a wired infrastructure to locations where cabling is not possible or inefficient to implement.
In IEEE802.11 terminology a "Distribution System" is system that interconnects so-called Basic Service Sets(BSS). A BSS is best compared to a "cell", driven by a single Access Point. So a "Distribution system" connects cells in order to build a premise wide networknwhich allows users of mobile equipment to roam and stay connected to the avaiable network resources.


Advanced Setup | NAT
Network Address Translation (NAT). NAT allows all of the computers on your home network to use one IP address. When using the NAT capability of the U.S. Robotics 802.11g Wireless Router , you can access the Internet from any computer on your home network without having to purchase more IP addresses from your ISP.


Advanced Setup | NAT | Address Mapping
Address Mapping allows multiple users at your local site to access the Internet through a single public IP address or multiple public IP addresses. By default, all the local IP addresses will map to the WAN IP address by default. The U.S. Robotics 802.11g Wireless Router also supports special mapping between a particular global IP (which is not the IP address of the WAN port) and a group of local IP's. This feature is particular useful when the user has multiple global IP's and can divide local users in different groups. Please note that the IP addresses will share the WAN port speed.




Advanced Setup | NAT | Virtual Server
You can configure the U.S. Robotics 802.11g Wireless Router as a virtual server so that remote users accessing services such as the Web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the U.S. Robotics 802.11g Wireless Router redirects the external service request to the appropriate server (located at another internal IP address).
Some of the applications and protocol/port numbers mapping are defined below:

Application	Protocol	Port Number
Telnet	TCP	23
FTP	TCP	21
SMTP	TCP	25
POP3	TCP	110
H.323	TCP	1720
SNMP	UCP	161
SNMP Trap	UDP	162
HTTP	TCP	80
PPTP	TCP	1723
PC Anywhere	TCP	5631
PC Anywhere	UDP	5632

Advanced Setup | NAT | Special Applications
Some applications require multiple connections, such as Internet gaming, and Instant Messaging. These applications cannot work when Network Address Translation (NAT) is enabled. If you need to run applications that require multiple connections, specify the port and/or port range associated with an application in the "Trigger Port" field, select the protocol type (TCP/UDP/BOTH) then enter the public ports associated with the trigger port/s to open them for inbound traffic.

Note:The range that you can use for all NAT ports is 0 to 65535.

Example:

ID	Trigger Port	Trigger Type	Public Port	Public Type	Comment
1	28800	TCP	2300-2400, 47624	TCP	MSN Game Zone
2	6112	UDP	6112	UDP	Battle.net

The U.S. Robotics 802.11g Wireless Router provides a Stateful Inspection firewall that is designed to protect against Denial of Service attacks when activated. Its purpose is to allow a private local area network (LAN) to be securely connected to the Internet. It covers the following features:

1. Access control list - allows users to define the traffic type permitted or not-permitted for outgoing traffic. Users can specify the traffic type by network/session layer header like source or destination IP address, port number etc...
   
2. Stateful Packet Inspection (SPI) - allows users to specify the incoming traffic permitted or not-permitted based on the application type. Such as TCP/UDP session, FTP session or H.323 session.
   
3. Denial of Service (DoS) Attack prevention - defends and protects local network (LAN) resources against common attacks such as Ping fragment flood and SYN flood.
   
4. Real-time logging - allows users to record the real-time firewall information for further use.
   

Access Control allows users to define the outgoing traffic permitted or not permitted for the WAN interface. By default the U.S. Robotics 802.11g Wireless Router allows all outgoing traffic. The rules defined under access control can limit the access of hosts within the local area network (LAN) by IP and MAC address, time and day. The U.S. Robotics 802.11g Wireless Router can also limit the access of PCs within the network by blocking specific ports. The Access Control feature can support up to 15 different access rules.

Application	Protocol	Port Number
Telnet	TCP	23
FTP	TCP	21
SMTP	TCP	25
POP3	TCP	110
H.323	TCP	1720
SNMP	UCP	161
SNMP Trap	UDP	162
HTTP	TCP	80
PPTP	TCP	1723
PC Anywhere	TCP	5631
PC Anywhere	UDP	5632

Advanced Setup | Firewall | MAC Filter

When enabled; only MAC addresses listed in this table will have access to your network. All other client devices will get denied access. This security feature can support up to 32 devices and applies to all clients.

The U.S. Robotics 802.11g Wireless Router allows the user to block access to certain Web sites from a particular PC by entering either a full URL address or keyword of the Web site. The U.S. Robotics 802.11g Wireless Router will examine all the HTTP packets to block the access to those particular sites. This feature can be used to protect children from accessing certain violent or sexual web sites.

Each access control rule can be activated at a pre-defined scheduled time. The user defines the schedule in the "Schedule Rule" page, and applies the rule in the "Access Control" page.

The U.S. Robotics 802.11g Wireless Router inspects packets at the application layer, and maintains TCP and UDP session information, including timeouts and the number of active sessions. The U.S. Robotics 802.11g Wireless Router also provides the ability to detect and prevent certain types of network attacks such as DoS attacks. Network attacks that deny access to a network device are called denial-of-service (DoS) attacks. Denials of Service (DoS) attacks are aimed at devices and networks with a connection to the Internet. The goal is not to steal information, but to disable a device or network so users no longer have access to network resources.
By using above inspected information and timeout/threshold criteria, the U.S. Robotics 802.11g Wireless Router provide following DoS attacks prevention: Ping of Death (Ping flood) attack, SYN flood attack, IP fragment attack (Teardrop Attact), Brute-force attack, Land Attack, IP Spoofing attack, IP with zero length, TCP null scan (Port Scan Attach), UDP port loopback, Snork Attack, and other potential attack types.

If you have a client PC that cannot run Internet application properly from behind the NAT firewall , then you can open the client to unrestricted two-way Internet access.
Enter the IP address of a DMZ hosts on this screen. Adding a client to the DMZ (Demilitarized Zone) may expose your local network to a variety of security risks; so only use this option as a last resort.

Dynamic DNS provides users on the Internet a method to tie their domain name(s) to computers or servers. DDNS allows your domain name to follow your IP address automatically by having your DNS records changed when your IP address changes.

The Universal Plug and Play architecture offers pervasive peer-to-peer network connectivity of PCs of all form factors, intelligent appliances, and wireless devices. UPnP enables seamless proximity networking in addition to control and data transfer among networked devices in the home, office and everywhere in between.
