automatically adds this interface to the default WAN trunk.
For general, the rest of the screen's options do not automatically adjust and you must
manually configure a policy route to add routing and SNAT settings for the interface.

interface. The format is brx, where x is 0 - 11. For example, br0, br3, and so on.

when it does not know how to route the packet to its destination. The gateway should
be on the same network as the interface.
Metric Enter the priority of the gateway (if any) on this interface. The ZyWALL/USG decides
which gateway to use based on this priority. The lower the number, the higher the
priority. If two or more gateways have the same priority, the ZyWALL/USG uses the one
