I am in a situation where I can't change the port forwarding rules of my router, and I would like to use a service like own cloud. I have a server with a fixed IP to which I can make a SSH tunnel. My two questions are:
By doing an ssh tunnel, all the data is transmitted through the server? (If there's a limit to the transfer rate at my server side it would be a problem).
Is there another way to circumvent the port forwarding on the router?
You'd need to forward an SSH port also. I'd be surprised if that was allowed by default on a router.
By doing an ssh tunnel, all the data is transmitted through the server?
Yes. An SSH tunnel is the "poor-man's VPN".
”I want to expose a local server behind a NAT or firewall to the internet.”
ngrokallows you to expose a ... server running on your local machine to the internet. Just tellngrokwhat port your ... server is listening on
ngrok http <http_port>
or
ngrok tcp <tcp_port>
-- Ngrok
An SSH tunnel would be more secure.
