This series has already covered a few basics about ~/.ssh/config in terms of how to simplify the usage of ssh tunnelling. In order to round this up a bit more, I will add some information you should be aware of about ~/.ssh/config. This is only intended to be a quick reminder about how it is

Now that you are able to create various forward or reverse SSH tunnels with lots of options and even simplify your live with ~/.ssh/config you probably also want to know how make a tunnel persistent. By persistent I mean, that it is made sure the tunnel will always run. For example, once your ssh connection
If you have read the previous article of this series, you should be able to create forward and reverse tunnels with ease. In addition to the previously shown examples I will address some more advanced options for SSH tunnels in general. Article series SSH tunnelling for fun and profit Local vs Remote Tunnel options AutoSSH
When it comes to the art of SSH tunnelling, there are basically two options where to relay a port to.
You can relay a port from a remote server to your local machine with `ssh -L`, hence called local port forwarding. A very basic use-case is if your remote server has a MySQL database daemon listening on port `3306` and you want to access this daemon from your local computer.
The second option is to make your local port available on a remote server (`ssh -R`). Remote port forwarding might come in handy if you for example want to make your local web-server available on a port of a public server, so that someone can quickly check what your local web-server provides without having to deploy it somewhere publicly.
