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 211).
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
