    Are you talking about ssh port forwarding?

    You would do this.

    ssh -L 5900:VNCServer:5900 user@sshserver

    you would then point your vncviewer at localhost. The session will go through the sshserver and then connect to the VNC Server

    No. I've got alot of clients with VNC Server on it. But I work athome, so I need to connect sometimes to other servers through my Firewall without ssh

    You'll need an open port for each of the servers you want to connect to.
    So that's basicaly 5900 for the first, 5901 for the second, etc, etc.
    These open ports will show up on a portscan on you firewall.
    It's better to use SSH tunneling to you firewall and then use a VNC forwarder from there to the various systems.
    I know that it's a bit slower, but it gives you far more security.
    There is a program available that runs like a 'terminal server' to multiple vnc servers. Can't remember the name though, try google.
    If you still want to open the ports let me know, I'll post the iptables rules for it.
