How does SSH dynamic port forwarding work?
Dynamic port forwarding allows you to create a socket on the local (ssh client) machine, which acts as a SOCKS proxy server. When a client connects to this port, the connection is forwarded to the remote (ssh server) machine, which is then forwarded to a dynamic port on the destination machine.

How can I forward ports using SSH?
you will need some service on your local machine that you want to expose publicly from another host.
How is SOCKS protocol used in SSH dynamic port forwarding?

The SOCKS protocol can be used to proxy a TCP connection from any port to any port on behalf of any client that supports the protocol. It is normally used at the permitter of corporate networks to regulate external internet access.
What is SSH tunneling or port forwarding?
Introduction. Port forwarding via SSH ( SSH tunneling) creates a secure connection between a local computer and a remote machine through which services can be relayed.
What is reverse SSH tunneling?
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. Because the original connection came from the remote computer to you, using it to go in the other direction is using it “in reverse.” And because SSH is secure,…
