Chapter 9 Device Network Settings Table 119 Device Operation > Device Configuration > Network > Routing > Policy Route > Edit (continued) LABEL DESCRIPTION Source Network Address Translation Select none to not use NAT for the route. Select outgoing-interface to use the IP address of the outgoing interface as the source IP address of the packets that matches this route. If you select outgoing-interface, you can also configure port trigger settings for this interface. To use SNAT for a virtual interface that is in the same WAN trunk as the physical interface to which the virtual interface is bound, the virtual interface and physical interface must be in different subnets. Port Triggering Otherwise, select a pre-defined address (group) to use as the source IP address(es) of the packets that match this route. Configure trigger port forwarding to allow computers on the LAN to dynamically take turns using a service that uses a dedicated range of ports on the client side and a dedicated range of ports on the server side. Note: You need to create a firewall rule to allow an incoming service before using a port triggering rule. # This is the rule index number. Incoming Service Select the service that the client computer sends to a remote server. The incoming service should have the same service or protocol type as what you configured in the Service field. Trigger Service Select a service that a remote server sends. It causes (triggers) the ZyWALL to forward the traffic (received on the outgoing interface) to the client computer that requested the service. Add icon Click the Add icon in the heading row to add a new first entry. Click the Add icon in an entry to add a rule below the current entry. Click the Remove icon to delete an existing rule from the ZyWALL. A window displays asking you to confirm that you want to delete the rule. In a numbered list, click the Move to N icon to display a field to type a number for where you want to put that rule and press [ENTER] to move the rule to the number that you typed. Total Records Bandwidth Shaping The ordering of your rules is important as they are applied in order of their numbering. This field displays the total number of trigger port forwarding entries. This allows you to allocate bandwidth to a route and prioritize traffic that matches the routing policy. You must also enable bandwidth management in the main policy route screen (Device Operation > Device Configuration > Network > Routing > Policy Route) in order to apply bandwidth shaping.
