NAT (Network Address Translation) Commands

ENABLE NAT

DISABLE NAT

Valid context: Profile, Port

Enables/disables NAT (Network Address Translation). NAT allows your router to use only one IP address when communicating with remote sites via the ADSL port, effectively 'hiding' connected devices. Enabled by default.

SHOW IP NAT

Displays the IP NAT table, which contains the settings for all computers on the internal LAN that are visible to the external network.

ADD IP NAT <UDP TCP> <port> <ipaddress>

DELETE IP NAT <UDP TCP> <port>

ADD IP NAT allows a computer on the internal LAN to be visible to the external network for a particular protocol. For example, if you want an internal computer to function as a SMTP (E-mail) server, set TCP to port 25 and enter the IP address of the computer.

Use DELETE IP NAT to remove the NAT assignment.

UDP TCP	UDP or TCP protocol.

<port>	Port to use.

<ipaddress>	IP address of the computer on the internal LAN.

SET IP NAT <UDP TCP> <port> <ipaddress>

Changes an existing entry in IP NAT table.

UDP TCP	UDP or TCP protocol.

<port>	Port to use.

<ipaddress>	IP address of the computer on the internal LAN.
