14.1 Interface Grouping Overview

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

14.1.1 What You Can Do in this Chapter

The Interface Grouping screen lets you create multiple networks on the Zyxel Device
page 170).

14.2 Interface Grouping

You can manually add a LAN interface to a new group. Alternatively, you can have the Zyxel 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 Setup screen to configure the private IP addresses the DHCP server on the Zyxel Device
assigns to the clients in the default and/or user-defined groups. If you set the Zyxel 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.
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.
