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 address is 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.
