15.1 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.

Devices in different groups cannot communicate with each other directly.

15.1.1 What You Can Do in this Chapter

The Interface Grouping screens let you map a port to a PVC or bridge group.

198).

15.2 Interface Grouping Setup

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.
