Configuring a DMZ Host
The CVR100W supports demilitarized zones (DMZ). A DMZ is a subnetwork that is
open to the public but behind the firewall. A DMZ allows you to redirect packets
going to your WAN port IP address to a particular IP address in your LAN.
We recommended that you place hosts that must be exposed to the WAN (such as
web or e-mail servers) in the DMZ network. You can configure firewall rules to
allow access to specific services and ports in the DMZ from both the LAN or WAN.
In the event of an attack on any of the DMZ nodes, the LAN is not necessarily
vulnerable.
You must configure a fixed (static) IP address for the endpoint that you designate
as the DMZ host. You should assign the DMZ host an IP address in the same
subnet as the CVR100W’s LAN IP address, but it cannot be identical to the IP
address given to the LAN interface of this gateway.

STEP 1
