Select Zone

Select the security zone that you want the interface to be a member of. If you
choose not to assign the interface to a zone, there is a strong possibility that traffic
will not pass through the interface.
ZPF Inside Zones
Zones that include interfaces used in generic routing encapsulation (GRE) tunnels
must be designated as inside (trusted) zones in order for GRE traffic to pass
through the firewall.
This window lists the configured zones and their member interfaces. To designate
a zone as inside, check the inside (trusted) column in the row for that zone.
