13.9 Virtual Interfaces
Use virtual interfaces to tell the ZyWALL where to route packets. Virtual interfaces
can also be used in VPN gateways (see Chapter 25 on page 441) and VRRP groups
(see Chapter 39 on page 667).
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.
Like other interfaces, virtual interfaces have an IP address, subnet mask, and
gateway used to make routing decisions. However, you have to manually specify
the IP address and subnet mask; virtual interfaces cannot be DHCP clients. Like
other interfaces, you can restrict bandwidth through virtual interfaces, but you
