CHAPTER 15
Interface Group
15.1 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 the 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.
15.1.1 What You Can Do in this Chapter
The Interface Group screens let you create multiple networks on the ZyXEL
Device (Section 15.2 on page 215).
15.2 The Interface Group Screen
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 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 Chapter 8 on
page 131 for more information.
