The vm-interface
is used by malware running on the WildFire appliance virtual machine
sandbox to access the Internet. Activating this port is recommended
and will help WildFire better identify malicious activity if the
malware accesses the Internet for phone-home or other activity.
It is important that this interface has an isolated connection to
the Internet. If your WildFire appliance is operating in FIPS/CC
mode, the vm-interface is disabled. For more information, see
Set
Up the WildFire Appliance VM Interface.
