set deviceconfig system vm-interface
The vm-interface is used by malware running on the WF-500 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. For more information, see
Set Up the WF-500 Appliance VM Interface.
