<h2>What is this?</h2>
|
||||
|
||||
<p>This is a reverse proxy service that uses SSH as the transport. It works similar to ngrok or localtunnel.me.</p>
|
||||
|
||||
<p>
|
||||
You run the service on a internet addressible host and ssh to it. Using ssh remote forwards (ie. ssh -R) the port
|
||||
on the remote host will be forwared to the configured port on your local machine.
|
||||
