Chapter 4: Configuring the Gateway
The Setup Tab
Wireless-G ADSL Gateway with 2 Phone Ports
Advanced Routing Tab
The Advanced Routing screen allows you to configure the dynamic routing and static routing settings.
Advanced Routing
Operating Mode
. 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
radio button.
Dynamic Routing/RIP
. With Dynamic Routing you can enable the Gateway to automatically adjust to physical
changes in the network’s layout. The Gateway, using the RIP protocol, 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. To enable RIP, click
Enabled
. To disable RIP,
click
Disabled
.
•
Transmit RIP Version. To transmit RIP messages, select the protocol you want:
RIP1, RIP1-Compatible,
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
. 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, after selecting the entry, click the
Delete This Entry
button.
•
Destination IP Address. The Destination 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. If you are building a route to an entire network, set the network portion of the IP address to 0.
•
Subnet Mask. The Subnet Mask (also known as the Network Mask) determines which portion of an IP
address is the network portion, and which portion is the host portion.
•
Gateway. This IP address should be the IP address of the gateway device that allows for contact between
the Gateway and the remote network or host.
