NETGEAR UTM50-100NAS, UTM5-100NAS manual Configuring and Enabling the DMZ Port

ProSecure Unified Threat Management (UTM) Appliance Reference Manual

To reserve an IP address, select Reserved (DHCP Client) from the IP Address Type pull-down menu on the LAN Groups screen as described in “Adding PCs or Devices to the Network Database” on page 4-15or on the Edit Groups and Hosts screen as described in “Editing PCs or Devices in the Network Database” on page 4-16.

Note: The reserved address is not assigned until the next time the PC or device contacts the UTM’s DHCP server. Reboot the PC or device, or access its IP configuration and force a DHCP release and renew.

Configuring and Enabling the DMZ Port

The De-Militarized Zone (DMZ) is a network that, by default, has fewer firewall restrictions when compared to the LAN. The DMZ can be used to host servers (such as a web server, FTP server, or e-mail server) and provide public access to them. The fourth LAN port on the UTM (the rightmost LAN port) can be dedicated as a hardware DMZ port to safely provide services to the Internet without compromising security on your LAN. 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 properly with them, but there are other applications that might not function well. In some cases, local PCs can run the application properly if those PCs are used on the DMZ port.

Note: A separate firewall security profile is provided for the DMZ port that is hardware- independent of the standard firewall security 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, see “Front Panel” on page 1-10) and configure an IP address and subnet mask for the DMZ port.
