DESCRIPTION
Select the WAN port to use the port forwarding rules.
This is the number of an individual entry.
Select this check box to enable the port forwarding entry. Clear this
check box to disallow forwarding of these ports to an inside server
without having to delete the entry.
Type a name to identify this port-forwarding rule. To delete a port
forwarding entry, erase the name, and click Apply.
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 this screen. If you do not assign a default server IP address, then all
packets received for ports not specified in this screen or remote
management will be discarded.
Enter a port number here. To forward only one port, enter it again in the
second field. To specify a range of ports, enter the last port to be
forwarded in the second field.
