4.10 Multiple Servers behind SUA
If you wish, you can make inside servers for different services, e.g., web or FTP, visible to the outside
users, even though SUA makes your whole inside network appear as a single machine to the outside world.
A service 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 an FTP server
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.
Please note that a server can support more than one service, e.g., a server can provide both FTP and DNS
service, while another provides only web service. Also, since you need to specify the IP address of a server
in the Prestige, a server must have a fixed IP address and not be a DHCP client whose IP address potentially
changes each time it is powered on.
