Cellular WAN interface
When you turn on cellular WAN, the firewall creates the WWAN1 interface. This interface is a member of the WAN zone, and the firewall rules for the WAN zone apply to it. The firewall also creates the ##WWAN1 host. You can protect against malware attacks and unauthorized usage by specifying firewall rules and policies for the host.
