NAT Server Sets
The NAT Server Set is a list of LAN side servers mapped to external ports
(similar to the old SUA menu of before). If you wish, you can make inside
servers for different services, e.g., Web or FTP, visible to the outside users,
even though NAT makes your network appears as a single machine to the
outside world. A server is identified by the port number, e.g., Web service is on
port 80 and FTP on port 21.
As an example (see the following figure), if you have a Web server at
192.168.1.36 and a FTP server at 192.168.1.33, then you need to specify for
port 80 (Web) the server at IP address 192.168.1.36 and for port 21 (FTP)
another at IP address 192.168.1.33.
