interfaces cannot be DHCP clients. The virtual interface uses the same MTU and bandwidth settings that
the underlying interface uses. Unlike other interfaces, virtual interfaces do not provide DHCP services,
and they do not verify that the gateway is available.
This screen lets you configure IP address assignment and interface parameters for virtual interfaces. To
access this screen, click the Create Virtual Interface icon in the Ethernet, VLAN, or bridge interface
summary screen.

LABEL DESCRIPTION
Interface Properties
Interface Name This field is read-only. It displays the name of the virtual interface, which is automatically
derived from the underlying Ethernet interface, VLAN interface, or bridge interface.
Description Enter a description of this interface. It is not used elsewhere. You can use alphanumeric and
()+/:=?!*#@$_%- characters, and it can be up to 60 characters long.
IP Address
Assignment
IP Address Enter the IP address for this interface.
Subnet Mask Enter the subnet mask of this interface in dot decimal notation. The subnet mask indicates
what part of the IP address is the same for all computers in the network.
Gateway Enter the IP address of the gateway. The Zyxel Device sends packets to the gateway when
it does not know how to route the packet to its destination. The gateway should be on the
same network as the interface.
Metric Enter the priority of the gateway (if any) on this interface. The Zyxel Device decides which
gateway to use based on this priority. The lower the number, the higher the priority. If two or
more gateways have the same priority, the Zyxel Device uses the one that was configured
first.
OK Click OK to save your changes back to the Zyxel Device.
Cancel Click Cancel to exit this screen without saving.
