Port forwarding via SSH (SSH tunneling) creates a secure connection between your server and a remote machine through which any number of services can be. That alone isn't sufficient for your needs, however, because it doesn't provide you with a working command-line session on the remote computer. How to Set up SSH Tunneling (Port Forwarding) Updated 8 min read SSH tunneling or SSH port forwarding is a method of creating an encrypted SSH connection between a client and a server machine through which services ports can be relayed. It really doesn't matter what the specific network issue is-this is useful whenever you can't SSH straight to a remote computer.Ä«ut if the networking configuration on your end is straightforward, the remote computer can connect to you. For creating a TUN tunnel, will leave here a practical script, from Ip Tunnel Over Ssh With Tun the script assumes you are running as root. That isn't an option in the networking scenario we're describing. 1 Answer Sorted by: 11 Using OpenSSH in Linux, tunnels can be created over SSH using either TUN or TAP interfaces, as long as proper routing is setup and ip forwarding where appropriate. Normally you'd fire up an SSH connection from the local computer and connect to the remote computer. In order for the tunnel setup to succeed you must be allowed to connect via ssh as, just as if you had attempted to use ssh to create a terminal. Here we can initiate an ssh tunnel in one direction, then use that tunnel to create an ssh tunnel back the other way. To differentiate between the local and remote computers used in this article, the remote computer is called "howtogeek" and is running Ubuntu Linux (with purple terminal windows). The local computer is called "Sulaco" and is running Manjaro Linux (with yellow terminal windows). This syntax to create a local ssh port forwarding tunnel is this: ssh -L :: Remote SSH Port Forwarding In this scenario we are creating a reverse ssh tunnel.SSH server listening for connections from the client. The computer you are going to connect to is the remote computer because it is in a different location than you. To create an SSH tunnel, you need: Target server offering network services (http, vnc, etc.) to the client. Your computer is the local computer because it is near you. ![]()
