Reverse Proxy with no HTTPD access

http://serverfault.com – I'll outline my requirement, proposed solution and if anyone has a better idea please feel free to suggest. Requirements / Desires - I want multiple clients to be connectible to an address myserver.com:4444 (arbitrary numbers chosen). I wish to then redirect the TCP traffic, invisible to the client, to my VPN. My VPN however randomly assigns a forwarding port so I have no control over what port is assigned, and it changes upon internet disconnection / shutdown etc. In other words, the clients connect to myserver.com:4444 and the server routes the traffic to myhomeip:54321. I would be happy / (HowTos)
