The site they are located at may have tight firewall rules in place, or perhaps the local admin has set up complex Network Address Translation rules. How do you reach such a computer if you need to connect to it?
Your computer is the local computer because it is near you. The computer you are going to connect to is the remote computer because it is in a different location than you. But if the networking configuration on your end is straightforward, the remote computer can connect to you. But it is a start. You have an established connection between the two computers. Reverse SSH tunneling allows you to use that established connection to set up a new connection from your local computer back to the remote computer.
This means your connection to the remote computer acts as a private tunnel inside the original connection. Reverse SSH tunneling relies on the remote computer using the established connection to listen for new connection requests from the local computer. The remote computer listens on a network port on the local computer. If it detects an SSH request to that port, it relays that connection request back to itself, down the established connection. This provides a new connection from the local computer to the remote computer.
You may get a warning about having never connected to the local computer before. Or you may see a warning as the connection details are added to the list of recognized SSH hosts. What you see—if anything—depends on whether connections have ever been made from the remote computer to the local computer. You will be prompted for the password of the account you are using to connect to the local computer. Note that when the connection has been made the command prompt changes from dave howtogeek to dave sulaco.
That means we can issue commands to it. We can see that the person with the user account called dave has logged in to the local computer, and the remote computer has connected using the same user credentials from IP address Because the connection from the remote computer is successful, and it is listening for connections, we can try to connect to the remote computer from the local one.
The remote computer is listening on port on the local computer. So—somewhat counter-intuitively—to make a connection to the remote computer, we ask ssh to make a connection the local computer, on port That connection request will be forward to the remote computer.
We are prompted for the user account password, then connected to the remote computer from the local computer. Note that the command prompt has changed from dave sulaco to dave howtogeek. To make it more convenient to connect from the remote computer to the local computer, we can set up SSH keys. You will be prompted for a passphrase. You can press Enter to ignore the passphrase questions, but this is not recommended. It would mean that anyone on the remote computer could make an SSH connection to your local computer without being challenged for a password.
You will be prompted for the password for the user account you are logging in to, in this case, dave sulaco. Asked 2 years, 1 month ago. Active 2 years, 1 month ago.

You can make new connections to a port on your home network forward to the internal IP address of your device. Opps, forgot to mention that. Yes i have, but it doesnt matter anyway because my isp blocks it at the edge router according to them.
All my port forwards work for any other protocol except ssh. I have tried it on , , ,, and no go. All firewalls were completely turned off for about 30 seconds to do testing. Nothing ever hit my server, no logs, nothin. Just times out. I even switched to my nieghboors xfinity access point, with their permission, and ssh server worked just fine haha. But my isp has confirmed that ssh is blocked. Im really hopping to learn how to do reverse ssh on a vps from a win So much to learn haha — Matt Thomas.
I'm voting to close this question as off-topic because I think this is an XY problem case. Add a comment. Active Oldest Votes. Several comments here: You don't need to install software to run it.

Just to test it, i set up a game server for a friend with a port forward in my router of I am OPEN to this solution.
I must have been ill-informe by previous forum telling me that vpn software can not be run portable. If this is by far the better solution, i am open to it. Still, learning the reverse ssh solution would be fun and educational.
So open vpn forums are telling me there is no such thing as a portable vpn client?? Improve this question. Add a comment.
