DESCRIPTION
Select this to have the ZyWALL use the IP address of the outgoing
interface as the source IP address of the packets it sends out through
its WAN trunks. The ZyWALL automatically adds SNAT settings for
traffic it routes from internal interfaces to external interfaces.
Select whether the ZyWALL is to use the default system WAN trunk or
one of the user configured WAN trunks as the default trunk for routing
traffic from internal interfaces to external interfaces.
The ZyWALL automatically adds all external interfaces into the pre-
configured system default SYSTEM_DEFAULT_WAN_TRUNK. You
cannot delete it. You can create your own User Configuration trunks.
Click this to create a new user-configured trunk.
Double-click an entry or select it and click Edit to open a screen where
you can modify the entry's settings.
To remove a user-configured trunk, select it and click Remove. The
ZyWALL confirms you want to remove it before doing so.
Select an entry and click Object References to open a screen that
shows which settings use the entry. See
for an example.
