Interface Grouping
11.1 Overview
By default, all LAN and WAN interfaces on the PMG2006-T20A are in the same group and can
communicate with each other. Create interface groups to have the PMG2006-T20A assign the IP
addresses in different domains to different groups. Each group acts as an independent network on the
PMG2006-T20A. 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.
11.1.1 What You Can Do in this Chapter
The
Interface Grouping
screens let you create multiple networks on the PMG2006-T20A (
11.2 The Interface Grouping Screen
You can manually add a LAN interface to a new group. Alternatively, you can have the PMG2006-T20A
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 PMG2006-T20A assigns
to the clients in the default and/or user-defined groups. If you set the PMG2006-T20A 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.
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.
