The RDR rule: Allowing external access to a LAN computer

You can create an RDR rule to make a computer on your LAN, such as a Web or FTP server, available to Internet users without requiring you to obtain a public IP address for that computer. The computer's private IP addressis translated to your public IP address in all incoming and outgoing data packets.

Note: Without an RDR rule (or Bimap rule described on page 76) the ADSL Barricade blocks attempts by external computers to access your LAN computers.
