DESCRIPTION
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, the ZyXEL Device discards all packets received for ports that
are not specified here or in the remote management setup.
Select a service from the drop-down list box.
Enter the IP address of the server for the specified service.
Click this button to add a rule to the table below.
This is the rule index number (read-only).

it.

forwarding rule.
