Web User Interface
Overview
The Web User Interface (WUI) is one of three router user interfaces. The other interfaces
are the Terminal User Interface (TUI) and Command Line Interface (CLI). Each interface
allows you to set up, modify, and view router configuration variables and operational data.
The Web User Interface is a system of graphical menus. Menu pages control router
parameters and provide information about them. The WUI organizes these router
parameters into six topics. Here are the six topics, in the order that the WUI displays them...
• Quick Setup • Firewall Settings
• Service Provider
Settings
• Tools
• Network Settings • Statistics
This part of the manual discusses all but the Quick Setup topic. You’ll find information on
using the Quick Setup feature in the Quick Installation Guide.
This manual begins topic discussions with a picture of the top-level menu screen. A
description of screen terms and procedures follows each screen shot. Either text or a table
defines screen variables. Afterward, summarized, step-by-step procedures often follow.
Selecting Topics. When you look at a menu page, notice the divider tabs at the very top of
the page. You can access any of the six router configuration and information topics by
clicking on its tab. The graphic below portrays the six divider tabs as they appear on a
menu.

ADSL Standard
The ADSL Standard menu configures the ADSL protocol. You’ll find four supported
protocols: Multi-mode, T1.413, G.dmt and G.lite. Your ISP determines the protocol to use.
In most cases, Multi-mode should allow a connection to the ISP.
PPPoE Relay
PPPoE Relay protocol supports multiple PPPoE sessions through the router, on a LAN
interface, over an RFC1483 Bridged PVC. The router supports multiple sessions by
maintaining a mapping table. In this table, each entry represents one session. The Client /
file:///P|/T_WRITER/Documentation/Released/900...ide/9003%20(Guiness)%20prac%20template/wui.htm (5 of 55) [11/6/2002 8:53:37 AM]
U.S. Robotics SureConnect ADSL Ethernet/USB Router User Guide
Server side MAC address and the Session Id provide the basis for the mapping. Refer to
WAN setup instructions on configuring PPPoE. The PPPoE Relay option requires an ATM
PVC (server) and a LAN interface (client). The client initiates a PPPoE session with the
server via a third-party PPPoE client. Follow these steps…
1. Configure the client and server.
2. Click Enable to start the relay function.
NAPT Bridge
This screen provides the option of enabling or disabling MER PVC. From this screen, you
can also change this PVC’s ATM values. The MER Interface is an RFC1483 Bridged PVC,
terminated in the router with a static public address. The ISP provides the static public
address. This type PVC operates with Network Address Translation (NAT) and DHCP.
These protocols allow the router to serve LAN users with private addresses.

Use LAN Setup to set the router’s IP Address and Subnet Mask. The LAN IP address
allows you to connect the router to your LAN. This address also allows you to manage the
router from your LAN. A LAN (Local Area Network) connects computers in the same
building or area.
Subnet masks split one network into a set of mini networks or subnets. Subnetting helps to
reduce traffic on each subnet. Subnetting also makes the network more manageable. Each
subnet functions as if it were an independent network.
To set up the LAN…
1. Enter the LAN IP Address for the router to use on the network.
2. Enter the Subnet Mask for the network that the router connects to.
3. Click Apply.
NOTICE. The LAN setup process changes the IP address of the Web User Interface. The
apply action causes the router to save your current configuration and then restart. After the
router restarts, you'll have to reapply to the Web User Interface using a new IP address.

•Gateway. IP address of the Default Gateway or Router that the node will use.
•Netmask. Subnet Mask for the LAN that the node will be on.
•DNS. Domain Name Server. The DNS that the node will use. DNS is a server with a
database. The database translates a domain name into a corresponding IP address. For
example, “USR.com” resolves into IP address 231.222.320.4. Communications over the
LAN between the node and USR.com web site use this address.
•Lease Time. Number of days that the node can use a DHCP lease. Subsequently, you
must renew the lease with the DHCP server.
DHCP Relay
Suppose that a Dynamic Host Configuration Protocol (DHCP) server resides on a different
LAN than the node broadcasting for DHCP service. Then the DHCP broadcast request must
be forwarded across the router/WAN to a subnet where a DHCP server resides. The router
must relay the DHCP request. DHCP relay assures that the requesting node receives an IP
address that corresponds to the node’s subnet. The router must have a record of the DHCP
server’s IP address. With this address, the router can correctly direct the request to the
appropriate DHCP server.
After you input the IP address into the menu, start the relay agent by clicking Start.

U.S. Robotics SureConnect ADSL Ethernet/USB Router User Guide
DNS Relay
The DNS Relay function supports forwarding of DNS requests from a LAN node to a known
DNS server.
•Domain Name. Internet site address that the router is a group of (i.e. usr.com).
•Primary DNS Server. IP address of the Primary DNS that the router will use. Domain
Name Server (DNS) is a server with a database. This server translates a domain name into
the corresponding IP address. For example, USR.com resolves into IP address
231.222.320.4. Communications over the LAN between the node and web site USR.com
use this address.
•Secondary DNS Server. IP address of the Secondary DNS that the router will use.
•Gateway. IP address of the Default Gateway the Router is to use.
•DNS Relay. Enabling or Disabling router ability to convey a DNS request from a LAN node.

Routing Setup
A router forwards data packets between local area networks (LANs) or wide area networks
(WANs). Based on routing tables and routing protocols, routers read the network address in
each transmitted packet. Routers then decide where to send the packet. A router bases this
decision on the best route. The Routing Setup menu allows the user to configure how the
router forwards received IP packets.
RIP Information
Routing Information Protocol (RIP) is a routing protocol and is part of the TCP/IP suite. RIP
determines a route based on the smallest hop count between source and destination. RIP
determines the smallest hop count by communicating with other routers within the network.
Only use RIP if the target router also utilizes RIP.
•RIP Status=On/Off selection.
•Version= Version 1 (RIP1) or Version 2 (RIP2). Should match RIP versions used by other
routers in the network.
To save and install RIP data…

Spanning Tree-Bridging
Transparent bridges use the spanning tree algorithm to dynamically determine the best
source-to- destination path. This algorithm avoids bridge loops (multiple paths linking one
segment to another) within a network. The algorithm determines all redundant paths and
