Configuring a DMZ Network
In addition to the LAN network, the Nokia IP45 security platform allows you to define a second
internal network called a demilitarized zone (DMZ).
By default, all traffic is allowed from the LAN network to the DMZ network, and no traffic is
allowed from the DMZ network to the LAN network. You can customize this behavior by
creating firewall user rules.
For example, you can assign your company accounting department to the LAN network and the
rest of the company to the DMZ network. The accounting department would be able to connect
to all company computers, while the rest of the employees cannot access any sensitive
information on the accounting department computers. You can then create firewall rules that
allow specific computers (such as a manager’s computer) to connect to the LAN network and the
accounting department.

Nokia IP45 v4.0 supports DMZ as WAN2. That is, the DMZ port can serve as a secondary WAN
port. When the DMZ port is assigned to WAN2, the primary Internet connection uses the WAN
port, and the secondary uses the DMZ port. For more information about configuring ports, see
“Managing Ports”
on page 124.
When this option is not in use, you can configure two Internet connections that share the same
WAN port.
Note
The DHCP server is supported on a DMZ network.
The following procedure describes about how to configure and edit DMZ networks by using the
Nokia IP45 graphical user interface:
To configure or edit DMZ network
1.
Choose Network > My Network page, and click Edit next to DMZ.
The Edit Network Settings page opens.
2.
From the Mode drop-down list, select Enabled.
3.
In the IP Address text box, enter the IP address of the DMZ network default gateway.
Note
The DMZ network must not overlap the LAN network.
4.
Enter the value of the subnet mask.
5.
From the Hide NAT drop-down list, select Enabled or Disabled.
