The Advanced Routing Tab
The Advanced Routing screen allows you to configure NAT (Network Address Translation), dynamic routing, static
routing, and PVC routing settings.
Advanced Routing
• Operating Mode. In this section, you can disable or enable the Network Address Translation (NAT) feature.
• NAT. NAT is a security feature that is enabled by default. It enables the Gateway to translate IP addresses
of your LAN to a different IP address for the Internet. To disable NAT, click the Disable button.
• Dynamic Routing. If you have one or more other gateways or routers on your network, you may need to enable
dynamic routing, static routing, or both. In dynamic routing, the Gateway learns routes to other networks by
periodically communicating with other gateways and routers using RIP, the Routing Information Protocol.
Dynamic routing lets the Gateway automatically adjust to changes in the network's layout.
• RIP. If you have multiple routers, you may want to use RIP so the routers can exchange routing information
with each other. To use RIP, select the Enabled radio button. Otherwise, keep the default, Disabled.
• Transmit RIP Version. To transmit RIP messages, select the protocol you want: RIP1, RIP1-Compatible
(RIP1 broadcasts and RIP2 multicasts), or RIP2. If you don't want to transmit RIP messages, select
Disable.
• Receive RIP Version. To receive RIP messages, select the protocol you want: RIP1 or RIP2. If you don't
want to receive RIP messages, select Disable.
• Static Routing. For static routing, you input fixed routes to other networks by hand. This can be done to
ensure that information travels by the most efficient path, or to avoid the overhead of RIP. To create a static
route, change the following settings:
• Select set number. Select the number of the static route from the drop-down menu. The Gateway
supports up to 20 static route entries. If you need to delete a route, then select the entry and click the
Delete This Entry button.
• Destination IP Address. The Destination IP Address is the IP address of the remote network or host that
will be reached through the static route. Note that a network address almost always ends in 0, and a host
address never ends in 0.
• Subnet Mask. Enter the Subnet Mask (also known as the Network Mask), which determines which portion
of an IP address is the network portion, and which portion is the host portion.
