9.3.3 Virtual Interfaces
Use virtual interfaces to tell the Zyxel Device where to route packets. Virtual interfaces can also be used
in VPN gateways (see Chapter 20 on page 379) and VRRP groups (see Chapter 35 on page 675).
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, security policies) 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

LABEL DESCRIPTION
Interface Name This identifies the interface for which the configuration settings that use it are displayed.
Address Type Choose IPv4 Address, or IPv4 CIDR (for example, 192.168.1.1/24) or an IPv4 Range (for
example, 192.168.1.2-192.168.1.100) and then enter the target IP address information. The
Zyxel Device answers external ARP requests only if they match one of these inputted target IP
addresses. For example, if the IPv4 Address is 192.168.1.5, then the Zyxel Device will answer
ARP requests coming from the WAN only if it contains 192.168.1.5 as the target IP address.
