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
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???
