Chapter 2. Planning for Router Configuration 35

DNS Internet Account Information (optional)

The Domain Name Service (DNS) maps host names to IP addresses. DNS is performed by Domain

Name Servers. The router can get DNS information automatically. Or, you can choose to configure DNS

manually. Consult with your Network Service Provider to determine if you need to enter the following

information:

¥ DNS server address

¥ DNS second server address

¥ DNS domain name

IP Routing Addresses

For the Ethernet Interface

This information is defined by the user or your Network Administrator.

Ethernet IP Address (local LAN)

An Ethernet LAN IP address and subnet mask are required for the routerÕs local Ethernet LAN

connection.

Note: An Ethernet route is usually defined when there are multiple routers on the Ethernet that cannot

exchange routing information. This feature is not normally used, except in special circumstances.

For the WAN Interface

This information is defined by the Network Service Provider.

Source (Target/Local) WAN Port Address

If Network Address Translation (NAT) is enabled, you must specify a source WAN IP address for the

WAN connection to the remote router if IP address negotiation under PPP does not provide one. Check

with your system administrator for details on whether the router must communicate in numbered or

unnumbered mode and which addresses are required.

Remote WAN Address

You may need to specify a remote WAN IP address for the WAN connection to the remote router

depending on IP address negotiation under PPP. Check with your system administrator for details on

whether the router must communicate in numbered or unnumbered mode and which addresses are

required.

TCP/IP Remote Routes

An IP route includes an IP address, subnet mask, and metric (a number representing the perceived cost in

reaching the remote network or station).

A TCP/IP Default Route should be designated in the routing table for all traffic that cannot be directed

to other specific routes. Define the default route to a remote router or, in special circumstances, define an

Ethernet gateway. There can be only one default route specified.
