Destination IP Address: This parameter specifies the IP network address of the final
destination.
IP Subnet Mask: Enter the subnet mask for this destination.
Gateway IP Address: Enter the IP address of the gateway. The gateway is an immediate
neighbor of your ADSL modem router that will forward the packet to the destination. On the
LAN, the gateway must be a router on the same segment as your Router; over Internet
(WAN), the gateway must be the IP address of one of the remote nodes.
Metric: Metric represents the "cost" of transmission for routing purposes. IP Routing uses
hop count as the measurement of cost, with a minimum of 1 for directly connected networks.
Enter a number that approximates the cost for this link. The number need not to be precise,
but it must between 1 and 15. In practice, 2 or 3 is usually a good number.
Announced in RIP: This parameter determines if the ADSL modem router will include the
route to this remote node in its RIP broadcasts. If set to Yes, the route to this remote node will
be propagated to other hosts through RIP broadcasts. If No, this route is kept private and is
not included in RIP broadcasts.

Choose “Advanced Setup→NAT” menu, you can setup the NAT (Network Address Translation)
