A Demilitarized Zone (DMZ) is a secure server that adds an additional layer of security to the network and acts as a buffer between a local area network (LAN) and a less secure network such as the Internet. A DMZ is typically set up to allow local host's access to the Internet for special services such as gaming and video conferencing. A DMZ allows the user to redirect packets received on the WAN port to a particular IP address in the LAN.
The user must configure a fixed (static) IP address for the endpoint that is to be designated as the DMZ host. The DMZ host should be given an IP address in the same subnet as the LAN IP address of the device. The DMZ IP cannot be identical to the IP address given to the LAN interface of the gateway. This article explains how to configure a DMZ on the CVR100W VPN Router.
Step 1. Log in to the web configuration utility and choose Networking > LAN > DMZ Host. The DMZ Host page opens:
Step 2. The DMZ Hosting feature allows a local host to access the Internet for special services such as gaming and video conferencing. To use this feature, check Enable.
Step 3. From the VLAN drop-down list, choose the VLAN where the DMZ is enabled.
Step 4. Enter the IP address of the computer to be used as the DMZ in the DMZ Host IP Address field.
Step 5. Click Save to apply changes.
