Advanced Routing                                                          

NAT

NAT is Network Address Translation, which allows multiple computers to share one Internet connection.  You can turn off NAT by selecting the Disable option.  By default, NAT is set to Enable.

Dynamic Routing

The Dynamic Routing feature can be used to automatically adjust to physical changes in the network's layout. The Gateway uses the dynamic RIP protocol. It determines the route that the network packets take based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other routers on the network.

To set up Dynamic Routing:

  1. Select Enabled for RIP mode.
  2. For the Transmit RIP Version dropdown menu, select the protocol you want to use for transmitting data on the network protocol you want for transmitting data on the network.
  3. For the Receive RIP Version dropdown menu, select the protocol you want to use for receiving data from the network.
  4. Click the Save Settings button to save your changes.

Static Routing

When multiple routers are installed on your network, you will need to configure Static Routing. The static routing function determines the path that data follows over your network before and after it passes through the Gateway. You can use static routing to allow different IP domain users to access the Internet through the Gateway. This is an advanced feature. Please proceed with caution.

To set up static routing, you should add routing entries in the Gateway's table that tell the device where to send all incoming packets. All of your network routers should direct the default route entry to this Gateway.

To create a static route entry:

  1. Select an entry from the drop down list. The Gateway supports up to 20 static route entries.
  2. Enter the following data for the static route.

    Destination IP Address

    Enter the network address of the remote local LAN segment.  For a standard Class C IP domain, the network address is the first three fields of the Destination LAN IP, while the last field should be zero.

    Subnet Mask

    Enter the Subnet Mask used on the destination IP domain.  For a standard class C IP domain, the Subnet Mask is 255.255.255.0.

    Gateway

    If this Gateway is used to connect your network to the Internet, then your Gateway IP is the Gateway's IP Address.  If you have another router handling your network's Internet connection, enter the IP Address of that router instead.

    Hop Count

    Enter the Hop Count.  This is the number of hops to each node until the destination has been reached.

  3. Click the Save Settings button to save your changes. Click Cancel Changes to cancel  your changes.

To view the current routing table, click the Show Routing Table button.

To delete  a static route entry:

  1. Select an entry from the drop-down list.
  2. Click the Delete Entry button.
  3. Click the Save Settings button to save your changes.
