Prestige 642R Series ADSL Router
3-16 Internet Access
Please note that a server can support more than one service, e.g., a server can provide both FTP and DNS
service, while another provides only web service. 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.
To make a server visible to the outside world, specify the port number of the service and the inside IP address
of the server in
Menu 15 – SUA Server Setup.
