Configuring Network Address Translation

you specify. For example, if your Web server uses (non- standard) port 2000, but you expect incoming data packets to refer to (standard) port 80, you should enter 2000 here (and select HTTP or type 80 in the Destination Port fields). The headers of incoming packets destined for port 80 will be modified to refer to port 2000. The packet will then be routed appropriately to the web server.

The Basic rule: Performing 1:1 translations

The Basic flavor translates the private (LAN-side) IP address to a public (WAN-side) address, like NAPT rules.

Therefore, the Basic rule does not provide the same level of security as the NAPT rule.
