Introduction 

If you wish, you can make internal servers (e.g., Web, ftp or mail server) accessible for outside users, 

even though SUA makes your LAN appear as a single machine to the outside world. A service is 

identified by the port number. 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.   

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.

Configuration 

To make a server visible to the outside world, specify the port number of the service and the inside 

address of the server in Network > NAT > Port Forwarding. The outside users can access the local server 

using the Prestige's WAN IP

address. 

For example (Configuring internal FTP, Telnet, and emule server for outside access) each on a different 

PC you would have to make configuration as follow:
