![]() ![]() Open command prompt (or a terminal if you’re on Linux), and log in to the server through SSH. On the local, install python3 and ssh, then. For reverse connection, this would be the following. This is required if you want to make the server listen to connections coming on ports below 1024, so-called privileged ports. 1 Answer Sorted by: 1 The simplest way to test a ssh tunnel is with the telnet command and with a python http server. Try to set up the server in such a way that you get to log in to the root account directly, preferably with an SSH key, as it’s more secure. You have access to the office’s SSH server at, and your user account on the SSH server is bob. Prepare Virtual Private Server to Tunnel ConnectionsĬreate a Virtual Private Server with your favorite provider, like DigitalOcean, Linode, Vultr, or whatever else you prefer. The most important thing is to choose a server location that is as close to you as possible to minimize network latency. The syntax is: ssh -L localport:remoteaddress:remoteport For example, let’s say the database server at your office is located at 192.168.1.111 on the office network. Read the tutorial about Windows 10’s OpenSSH client if you’re not already familiar with it. In fact, for this tutorial you will actually use this built-in client to set up the tunnel. There’s no need to use PuTTY anymore to initiate SSH connections. Learn how to setup a reverse SSH tunnel by way of an easy to understand example that allows a local service to be securely accessible by a remote connection. UDP tunneling is possible, but with some “hacks,” which may be the topic of a future tutorial. UDP is used by some (not all) game servers, for example Counter Strike (port 27015/UDP). TCP is used by things such as web servers (port 80/tcp). Note: This only works for redirecting TCP network traffic. That’s way cheaper than the monthly bill for a server with 6TB of space. You only have to pay a monthly electricity bill and less than $5/month for a virtual private server. You get the privacy of having those files on your home server, and then you can buy a 6TB hard drive to get all the space you need. ![]() ![]() There is a firewall between Windows PC Local and the Network A Linux Server that only allows me to SSH from PC local to the Linux Server on Network A. Imagine you create a NextCloud server to upload/synchronize your files. If you would like to establish more connections using reverse SSH tunneling, repeat Step 4 of this guide on a different port (e.g. 1 How would I use SSH Tunneling for an architecture in the example below Scenario: I am physically logged into Windows PC Local and wish to remote desktop into the Windows PC Remote using port 3389. plink. With the plink.exe, you use the same arguments as with the OpenSSH ssh, except for the -f, which does not have an equivalent in Windows. The server will receive incoming connections and redirect them to your computer through what is called a “reverse SSH tunnel.” This way you can set up any kind of home server, with very small monthly costs. 5 Answers Sorted by: 32 With the PuTTY suite, you can set up a tunnel either using the PuTTY itself (GUI) or using the command-line tool plink.exe. Anything will work, even if it has less than 512MB of RAM, as all it has to do is redirect network traffic. You can bypass all of these restrictions with the help of a virtual private server. ![]()
