The Setup Tab - Advanced Routing
The Advanced Routing screen allows you to configure the Network Address Translation (NAT), dynamic routing,
and static routing settings.
Advanced Routing
NAT
NAT is a security feature that is enabled by default. It enables the Router to translate IP addresses of your local
area network to a different IP address for the Internet. To disable NAT, click the Disable radio button. (When NAT
is disabled, the DHCP server feature is also disabled.)
Dynamic Routing
This feature enables the Router to automatically adjust to physical changes in the network’s layout and exchange
routing tables with the other router(s). The Router determines the network packets’ route based on the fewest
number of hops between the source and the destination.
Transmit RIP Version. To use dynamic routing for transmission of network data, select the protocol you want:
RIP1, RIP1-Compatible, or RIP2.
Receive RIP Version. To use dynamic routing for reception of network data, select the protocol you want, RIP1
or RIP2.
Static Routing
Use this feature to set up a static router between the Router and another network. (A static route is a pre-
determined pathway that network information must travel to reach a specific host or network.) To create a static
route, alter the following settings:
Select Entry. Select the number of the static route from the drop-down menu. The Router supports up to 20
static route entries.
Destination IP Address. The Destination LAN IP Address is the address of the remote network or host to which
you want to assign a static route. Enter the IP address of the host for which you wish to create a static route.
Subnet Mask. The Subnet Mask determines which portion of a Destination IP address is the network portion, and
which portion is the host portion.
