Configure and Enable the DMZ Port

The demilitarized zone (DMZ) is a network that, by default, has fewer firewall restrictions than the LAN. The DMZ can be used to host servers (such as a web server, FTP server, or email server) and provide public access to them. The rightmost LAN port on the UTM can be dedicated as a hardware DMZ port to provide services to the Internet safely without compromising security on your LAN. On the UTM5, UTM10, UTM25, and UTM150, this is LAN port 4; on the UTM50, this is LAN port 6.

By default, the DMZ port and both inbound and outbound DMZ traffic are disabled. Enabling the DMZ port and allowing traffic to and from the DMZ increases the traffic through the WAN ports.

Using a DMZ port is also helpful with online games and videoconferencing applications that are incompatible with NAT. The UTM is programmed to recognize some of these applications and to work correctly with them, but there are other applications that might not function well. In some cases, local computers can run the application correctly if those computers are used on the DMZ port.

Note: A separate firewall security profile is provided for the DMZ port that is also physically independent of the standard firewall security component that is used for the LAN.

The DMZ Setup screen lets you set up the DMZ port. It permits you to enable or disable the hardware DMZ port (LAN port 4 or LAN port 6; see Front Panel UTM5 and UTM10 on page 25) and configure an IP address and subnet mask for the DMZ port.

To enable and configure the DMZ port:

1. Select Network Config > DMZ Setup. The DMZ Setup screen displays:
