ADSL2+ Gateway with VoIP
The Setup - Advanced Routing Tab
The Advanced Routing screen allows you to configure the NAT, dynamic routing, and static routing settings.
Advanced Routing
Operating Mode.
In this section, you will configure the Gateway's general routing settings.
NAT. NAT is a security feature that is enabled by default. It enables the Gateway to translate IP addresses of your
local area network to a different IP address for the Internet. To disable NAT, click the Disabled option.
Dynamic Routing
With Dynamic Routing you can enable the Gateway to automatically adjust to physical changes in the network's
layout. Using RIP, the Gateway determines the network packets' route based on the fewest number of hops
between the source and the destination. The RIP protocol regularly broadcasts routing information to other
Gateways on the network.
RIP. If you have multiple routers, you may want to use the Routing Information Protocol (RIP) so the routers can
exchange routing information with each other. To use RIP, select the Enabled option. 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 None.
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 None.
Static Routing
If the Gateway is connected to more than one network, it may be necessary to set up a static route between
them. 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, 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.
