DESCRIPTION
Network Address Translation (NAT) allows the translation of an Internet protocol address used
within one network (for example a private IP address used in a local network) to a different IP
address known within another network (for example a public IP address used on the
Internet).
Select Enable to activate NAT. Select Disable to turn it off.
You can decide whether you want to use the default server or specify a server manually. In
addition to the servers for specified services, NAT supports a default server. A default server
receives packets from ports that are not specified in the port forwarding summary table
below.
Select this to use the default server.
Select this and manually enter the server's IP address.
Select Enable to allow port forwarding. Otherwise, select Disable.
This number uniquely identifies the port forwarding rule.
This field displays a name to identify this rule.
This is the transport layer protocol used for the service.
This is the port number used to connect to this service using the router's external IP address on
the WAN.
This field displays the internal IP address of the server.
This is the port number used to connect to this service using the server's internal IP address on
the LAN.
