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

You can manually add a LAN interface to a new group. Alternatively, you can have the XMG
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.

clients in the default and/or user-defined groups. If you set the XMG 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
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.
