DESCRIPTION
Select this to have the USG use the IP address of the outgoing interface as the
source IP address of the packets it sends out through its WAN trunks. The USG
automatically adds SNAT settings for traffic it routes from internal interfaces to
external interfaces.
Select whether the USG 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 USG 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 and customize the algorithm, member
interfaces and the active/passive mode.
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 USG confirms
you want to remove it before doing so.

settings use the entry. See
