Full Discussion: WebSocket over SSH tunnel - is it possible?
Special Forums IP Networking Proxy Server WebSocket over SSH tunnel - is it possible? Post 302931498 by Vladislav on Tuesday 13th of January 2015 11:13:10 AM

The setup is quite simple actually - there is a WebSocket server and a WebSocket client connecting to it.

My idea is to be able to indirectly access the WebSocket server by forwarding it's listening port to a machine with a real IP address. (in the case when the server is behind a router or firewall and using standard NAT forwarding / routing is not an option - e.g. on two devices accessing the Internet through a mobile data connection)

The problem is that the WebSocket client will always allocate a random port when initializing the communication and the SSH-relay point has no idea how to handle the responses coming from the server on that port.

What makes it even worse is that SSH will open yet another TCP socket (again on a random port) which will be then used to forward the client's request to the actual WebSocket server over the SSH tunnel.
So, if I want to make this work I will have to build a second SSH tunnel from the WebSocket client, in an attempt to bridge the SSH generated client socket to the original one, which makes this a somewhat complicated task...
