LAN-Cell 2 User’s Guide

The LAN-Cell supports three logical DMZ interfaces via its single physical DMZ Ethernet
interface. The LAN-Cell itself is the gateway for each of the logical DMZ networks.
The IP alias IP addresses can be either private or public regardless of whether the physical
DMZ interface is set to use a private or public IP address. Use NAT if you want to make DMZ
computers with private IP addresses publicly accessible (see Chapter 13 on page 289 for more
information). When you use IP alias, you can have the DMZ use both public and private IP
addresses at the same time.
" Make sure that the subnets of the logical networks do not overlap.
To change your LAN-Cell’s IP alias settings, click NETWORK > DMZ > IP Alias. The
screen appears as shown.

Select the check box to configure another DMZ network for the LAN-Cell.
IP Address Enter the IP address of your LAN-Cell in dotted decimal notation.
Note: Make sure the IP addresses of the LAN, WAN, WLAN and
DMZ are on separate subnets.
IP Subnet Mask Your LAN-Cell will automatically calculate the subnet mask based on the IP
address that you assign. Unless you are implementing subnetting, use the subnet
mask computed by the LAN-Cell.
