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.
Otherwise, select a pre-defined address (group) to use as the source IP
address(es) of the packets that match this route.
Use Create new Object if you need to configure a new address (group)
to use as the source IP address(es) of the packets that match this route.
Port Triggering 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.

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.
Bandwidth
Shaping 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
