NATD Port Forwarding question

Yes. It is a Windows 2000 Server machine that I can connect to both on
the local network and via an SSH tunnel. It is simply to do with natd's
port forwarding. I also cannot use port forwarding to access any other
services on the 2000 Server box such as telnet or ftp for example.

Any help is greatly appreciated.

Rgds,
Jon

Is the system configured to accept remote desktop requests? Windows XP
has it disabled by default.
