ZyWALL USG 100/200 Series User’s Guide

Use virtual interfaces to tell the ZyWALL where to route packets. Virtual interfaces can also 
be used in VPN gateways (see 

) and VRRP groups (see 

).

Virtual interfaces can be created on top of Ethernet interfaces, VLAN interfaces, or bridge 
interfaces. Virtual VLAN interfaces recognize and use the same VLAN ID. Otherwise, there is 
no difference between each type of virtual interface. Network policies (for example, firewall 
rules) that apply to the underlying interface automatically apply to the virtual interface as well.
