DOMAIN BLOCK TABLE

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.

DMZ Host IP Address — Specifies an IP address on the local network allowed unblocked access to the WAN.

NAT Loopback — Allows internal traffic to reach an internal LAN IP by using its public WAN IP.
