Interface Group; Chapter 13 Interface Group; Overview; What You Can Do In This Chapter - ZyXEL Communications VMG1312-B Series User Manual

13.1 Overview

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

13.1.1 What You Can Do in this Chapter

The Interface Group screens let you create multiple networks on the Device
page 203).

13.2 The Interface Group Screen

You can manually add a LAN interface to a new group. Alternatively, you can have the 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 Device assigns to
the clients in the default and/or user-defined groups. If you set the 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
137 for more information.
