CHAPTER 19
Interface Group
19.1 Overview
By default, all LAN and WAN interfaces on the P-870HN-51D are in the same
group and can communicate with each other. You can create multiple groups to
have the P-870HN-51D assign the IP addresses in different domains to different
groups. Each group acts as an independent network on the P-870HN-51D.
19.1.1 What You Can Do in this Chapter
The Interface Group screen lets you create multiple networks on the P-870HN-
51D (Section 19.2 on page 213).
19.2 The Interface Group Screen
You can manually add a LAN interface to a new group. Alternatively, you can have
the P-870HN-51D automatically add the incoming traffic and the LAN interface on
which traffic is received to the new group when its source MAC address or DHCP
option information matches the predefined filtering criteria.
Use the LAN screen to configure the private IP addresses the DHCP server on the
P-870HN-51D assigns to the clients in the default and/or user-defined groups. If
you set the P-870HN-51D to assign IP addresses based on the client’s source MAC
address or DHCP option information, you must enable DHCP server and configure
LAN TCP/IP settings for both the default and user-defined groups. See Chapter 6
on page 91 for more information.
