DMZ
DMZ enables a specified host PC on the local network to access the
Internet without any firewall protection. Some Internet applications, such
as interactive games or videoconferencing, may not function properly
behind the ADSL Router's firewall. By specifying a Demilitarized Zone
(DMZ) host, the PC's TCP ports are completely exposed to the Internet,
allowing open two-way communication. The host PC should be assigned a
static IP address.
