1. The -R (reverse) option tells ssh that new SSH sessions must be created on the remote computer.
2. The “43022:localhost:22” tells ssh that connection requests to port 43022 on the local computer should be forwarded to port 22 on the remote computer.

What is reverse SSH port forwarding?

Reverse SSH Port Forwarding specifies that the given port on the remote server host is to be forwarded to the given host and port on the local side. ... So instead of your machine doing a simple SSH, the server does an SSH and through the port forwarding makes sure that you can SSH back to the server machine.

With Two-Way SSH tunnel you can connect to any destination under a single condition, which is, the ability to ssh login from the destination to the source. If you can do that, you can as well reverse login from source to destination even if it is behind firewall or NAT.

How do you check if SSH tunnel is working Windows?

The simplest way to test a ssh tunnel is with the telnet command and with a python http server. For reverse connection, this would be the following. On the local, install python3 and ssh, then. >telnet localhost 8080 Trying 127.0.
