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', Port Forwarding Configuration. The outside users can access
the local server using the Prestige's
WAN IP
address.
