Virtual 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 ZyWALL 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 ZyWALL 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 ZyWALL uses 
the one that was configured first.
