Adding NAT Rules

5.In the [Global Address From:] and [Global Address To:] fields, type the public IP address assigned to you by your ISP.

If you have multiple WAN (PPP) interfaces, this rule will

not be enforced for data that arrives on other PPP interfaces. 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 more than one of them (or all), type the starting and ending IP addresses of the range.

6.In the [Destination Port From:] and [Destination Port To:] fields, type the port ID numbers of the computer you are making publicly available.

You can specify a range using the [From/To] fields if you want the rule to apply to a range of port types, or enter the same port number in both fields.

A port ID identifies the specific function of the computer connected to it, and therefore can limit the types of data that pass to and from the computer.

For example, Web (HTTP) servers are usually identified by port number 80; packets containing traffic destined for a Web server will contain this port ID. The Internet Assigned Numbers Authority (IANA) assigns port numbers for common types of servers and functions.

7.If the LAN computer that you are making publicly available is configured to use a non-standard port number for the type of traffic it receives, type the non-standard port number in the [Local Port:] field.

This option translates the standard port number in packets destined for your LAN computer to the non-standard number
