DESCRIPTION
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.
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.
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.
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.
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.
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.
