8.5.2 The RDR Rule

You can create a RDR rule to make a computer on your LAN, such as 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 for all incoming and outgoing data

packets.

NOTE! Without an RDR rule (or BIMAP rule), the HM210dp/di

blocks attempts by external computers to access your LAN

computers.

To create a RDR rule, proceed as follows:

1. Select Services > NAT > NAT Rule Entry > Add. The NAT Rule –

Add page appears:
