Interface Group
12.1  Overview
By default, all LAN and WAN interfaces on the Device are in the same group and can communicate 
with each other. Create interface groups to have the Device assign the IP addresses in different 
domains to different groups. Each group acts as an independent network on the Device. This lets 
devices connected to an interface group’s LAN interfaces communicate through the interface 
group’s WAN or LAN interfaces but not other WAN or LAN interfaces.
12.2  The Interface Group Screen
You can manually add a LAN interface to a new group. Alternatively, you can have the Device 
automatically add the incoming traffic and the LAN interface on which traffic is received to an 
interface group when its DHCP Vendor ID option information matches one listed for the interface 
group. 
Use the LAN screen to configure the private IP addresses the DHCP server on the Device assigns to 
the clients in the default and/or user-defined groups. If you set the Device to assign IP addresses 
based on the client’s DHCP Vendor ID option information, you must enable DHCP server and 
configure LAN TCP/IP settings for both the default and user-defined groups. See 
 for more information.
