I want to use VNC from the Java client on my work PC
to access a home PC.

Only standard ports are open on the firewall at work.

The home PC is connected via a NATed routed.

So on the NAT router I port forwarded port 21 to port
5800 on the PC running VNC server. So far so good -
the PC at work loads the JAVA client from the home PC
using

http://Home_router_publicIP:21

But when I enter the VNC password, the client then
complains there's no route to Home_router_publicIP. I
presume this because the JAVA client is then going
straight for port 5900???

    Yep, thats what the client wil be doing.

    Port forward 5900-590x (x = max simultaneous connections)
    to you home pc aswell.

    Should be fine then.

    Did this work? I am having the same problem with the
    tightVNC. In properties set the http to 23. At work I get the
    Java script. When I enter the password. It's states theres a
    network problem. Since I do not foward IPs how can I correct
    this? I am behind a firewall/gateway with only port 23
    passthrough. What other ports do I need to open?

    Actually how it looks:
    Port: 9090 HTTP:23...

    Any Ideas?
