Computer WebSocket over SSH tunnel - is it possible?
Hello,

I have a video streaming application that utilizes a WebSocket for the server <-> client communication. My goal is to make the video streaming service available over the internet in the cases where neither the server nor client have public IPs.

One way to do this is over a VPN connection, but I prefer not to use a VPN at all. That's why I decided to try and forward the communication over an SSH server via remote port forwarding.

However I am facing an issue - forwarding the server socket is pretty straight-forward, but I have no way to know in advance what the randomly allocated client port will be, so the traffic will flow only in the direction client -> SSH server -> streaming server.

When the SSH relay point receives the responses from the streaming server it does not automatically route them back to the client and the WebSocket handshake cannot be completed.

Do you think it is possible to overcome this issue or should I drop the WebSocket altogether and revert to a normal HTTP / TCP connection?

Thanks!
