Ugh! I am almost afraid to ask what country you are in! (I can guess...) Anyway, if port 22 is open, and if you can install an SSH client on your end and an SSH server on the other end, you can "tunnel" virtually any connection through the SSH connection. If the computer on the other end is any flavor of Unix (including Linux) it probably already has an SSH server on it; clients are widely available for Windows. This will have the added benefit of encrypting the entire connection. SSH also includes compression which may make the connection appear faster in a situation where you have fast computers and a slow network. For details on using VNC with SSH, see this page: http://www.uk.research.att.com/vnc/sshvnc.html Forwarding the VNC session through an SSH connection can also increase the security of the maching running the VNC server. The reason is that when SSH forwards a connection, the connection appears to be coming from the "localhost" rather than over the network. Therefore, you can run the VNC server with the localhost option, and it will reject all attempts to connect from other machines, and allow only local connections (including connections forwarded from SSH). I do this all the time to protect my home PC.
