Configure an Internal Server Behind the Prestige
•
Introduction
SUA makes your LAN appear as a single machine to the outside world. However, you can make a server (such
as a web server, FTP server or mail server) behind the ZyXEL device assessable/visible to the outside world. A
server behind the ZyXEL device cannot be set to be a DHCP client. That is, the server must use a fixed IP
address so outside users can access the server using the static IP address.
A service is identified by its standard port number. You can allow public access to servers for specified services
based on the port number. In addition, you can also set a default server behind SUA. Thus service requests that
do not match any of the servers are forwarded to the default server. If you do not set a default SUA server, then
the unknown service requests are simply discarded.

Configuration
To make an inside server visible to the outside world, specify the service port number and the IP address of the
server in SMT menu 15.2.1 - NAT Server Setup or the Port Forwarding screen in the web configurator. Users
use the WAN IP address of the Prestige to access the inside SUA servers. You can obtain the WAN IP address
of the Prestige in SMT menu 24.1.
