3.15 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, if you have a web server at 192.168.1.2 and a FTP server 192.168.1.3, then you need to
specify port 80 (web) to the server at IP address 192.168.1.2 and port 21 (FTP) for the FTP server
192.168.1.3.
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. Furthermore, 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.
In addition to the servers for specific services, SUA supports a default server. A service request that does
not have a server explicitly designated for it is forwarded to the default server. If the default server is not
defined, the service request is simply discarded.
To make a server visible to the outside world, specify the port number of the service and the inside IP
address of the server in
Menu 15 –
SUA Server Setup.
