LABEL	DESCRIPTION
Default Server	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 ZyWALL discards all packets
	received for ports that are not specified here or in the remote management setup.

Go To Page	Choose a page from the drop-down list box to display the corresponding summary
	page of the port forwarding servers.

Active	Select this check box to enable the port forwarding server entry. Clear this check
	box to disallow forwarding of these ports to an inside server without having to delete
	the entry.

Port Translation	Enter the port number here to which you want the ZyWALL to translate the incoming
	port. For a range of ports, you only need to enter the first number of the range to
