Interface Grouping
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. (
).
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.
