ZyWALL 2 Plus User's Guide
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 ZyWALL discards all packets
received for ports that are not specified here or in the remote management setup.
Choose a page from the drop-down list box to display the corresponding summary
page of the port forwarding servers.
This is the number of an individual port forwarding server entry.
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.
Enter a name to identify this port-forwarding rule.
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.
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
which you want the incoming ports translated, the ZyWALL automatically calculates
the last port of the translated port range.
Enter the inside IP address of the server here.
Click Apply to save your changes back to the ZyWALL.
Click Reset to begin configuring this screen afresh.
