Configure an Internal Server Behind SUA
•
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:
