15.1 Overview

By default, all LAN and WAN interfaces on the VMG are in the same group and can communicate
with each other. Create interface groups to have the VMG assign the IP addresses in different
domains to different groups. Each group acts as an independent network on the VMG. 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.

15.1.1 What You Can Do in this Chapter

The Interface Group screens let you create multiple networks on the VMG
183).

15.2 The Interface Group Screen

You can manually add a LAN interface to a new group. Alternatively, you can have the VMG
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 VMG assigns to
the clients in the default and/or user-defined groups. If you set the VMG 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
116 for more information.
In the following example, the client that sends packets with the DHCP Vendor ID option set to MSFT
5.0 (meaning it is a Windows 2000 DHCP client) is assigned the IP address 192.168.2.2 and uses
the WAN VDSL_PoE/ppp0.1 interface.
