NAT Settings — Enables NAT related settings.
• Network Address Translation – Enables the forwarding of TCP/UDP packets
• Network Address Translation – Enables the forwarding of TCP/UDP packets
through a NAT device.
• IPSec Pass Through – Enables tunnelling encrypted Internet Protocol Security
(IPSec) packets through a NAT device.
• PPTP Pass Through – Enables tunnelling Point-to-Point Tunneling Protocol
(PPTP) packets through a NAT device.
• L2TP Pass Through – Enables tunnelling Layer 2 Tunnelling Protocol (L2TP)
packets through a NAT device.
• SIP ALG – Allows SIP Application Layer Gateway (ALG) traversal filters to be used
to support address and port translation for certain application layer protocols.
• NetMeeting ALG – Allows NetMeeting ALG traversal filters to be used to support
address and port translation for certain application layer protocols.
• Window Messenger File Transfer ALG – Enables Window Messenger File
Transfer ALG to transmit packets through proxy servers.
• 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 wireless AP/
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 (which is
mapped to its MAC address) and this must be configured as the DMZ LAN IP.
