If you configure your home firewall to route port 5900 to port 5900 on
the destination computer, then you should be able to point your VNC

your firewall and it should just work.
It should even just work if you do that from within your home network,
although that depends a little on the firewall.
Do you know the IP address of your firewall? Not the 22.214.171.124
