¥ DNS Internet Account Information (optional)
This information is obtained from your Network Service Provider. Consult with you Network Service
Provider to find out 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. You will need to define the default route to a remote router or, in special
circumstances, define an Ethernet gateway. There can be only one default route specified.
