Web interface remote connection problem
 

I am trying to connect to my Suse 10.2 machine from a WinXp system running the web interface (using the port 5801).

I can connect to the linux machine writting its static ip on a web browser followed by :5801 and everything works fine.

But when I try to connect from a distant Pc (I have set up an account on Dyndns service) the interface stops right after entering the password in the "VNC Authentication - Password" field and I get the message: "network error: Connection reset by peer: connect"

Please note that using the VNC viewer enterprise edition (through Dyndns) works just fine from a remote pc.

Any ideas?
Thanks
