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:
