Network > Virtual Wires
Select Network > Virtual Wires to define virtual wires after you have specified two virtual wire interfaces on the firewall (Network > Interfaces).
Enter a virtual wire name (up to 31 characters). This name appears in the list of virtual wires when configuring interfaces. The name is case-sensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores.
Note: 
When utilizing virtual wire subinterfaces, the Tag Allowed list will cause all traffic with the listed tags to be classified to the parent virtual wire. Virtual wire subinterfaces must utilize tags that do not exist in the parent's Tag Allowed list.
