2.Define the rule ID and select the interface.
3.In the Local Address From/To fields, type the starting and ending IP addresses, respectively, of the range of private address you want to be translated. Or, type the same address in both fields to specify a single value.
If all LAN addresses should be translated, specify 0.0.0.0 and 255.255.255.255 respectively.
If you use
4.Complete as described for general procedure (steps 6 to 10).
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), the ADSL Router blocks attempts by external computers to access your LAN computers.
1.On the NAT Rule - Add page, select RDR from the Rule Flavor
2.Define the rule ID and select the interface.
3.From the Protocol
4.In the Local Address From/To fields, type the same private IP address, or the lowest and highest addresses in a range:
If you type the same IP address in both fields, incoming traffic that matches the criteria of this rule will be redirected to that IP address.
If you type a range of addresses, incoming traffic will be redirected to any available computer in that range. This option would typically be used for load balancing, whereby traffic is distributed among several redundant servers.
5.In the Global Address From/To fields, type the public IP address assigned to you by your ISP.
If you have multiple WAN interfaces, in both fields type the IP address of the interface to which this rule applies. This rule will not be enforced for data that arrives on WAN interfaces not specified here.
If you have multiple WAN interfaces and want the rule to be enforced on a range of them, type the starting and ending IP addresses of the range.
6.In the Destination Port From/To fields, enter the port ID (or a range) if incoming traffic destined for these port types should be redirected to the local port number specified in step 7.
