Chapter 17 Network Address Translation (NAT) Screens Figure 218 ADVANCED > NAT > Port Forwarding The following table describes the labels in this screen. Table 97 ADVANCED > NAT > Port Forwarding 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. # This is the number of an individual port forwarding server entry. 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. Name Enter a name to identify this port-forwarding rule. Incoming Port(s) 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. 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 which you want the incoming ports translated, the ZyWALL automatically calculates the last port of the translated port range. Server IP Address Enter the inside IP address of the server here. Apply Click Apply to save your changes back to the ZyWALL. Reset Click Reset to begin configuring this screen afresh.
