Configuring a DMZ Network

In addition to the LAN network, Nokia IP40 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 IP40 v2.0 supports DMZ as WAN2. That is, the DMZ port can now 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"
When this option is not in use, you can configure two Internet connections that share the same
WAN port.
