https://www.youtube.com/watch?v=AtuAdk4MwWw This video is mainly about different techniques about how to use SSH tunneling serving and maintaining access when not possible . i am actually adding this video particularly because of the graphic approach followed explaining how communication in the internet work , more precisely , IP PORTS . Types of Port Forwarding SSH's port forwarding feature can smuggle various types of Internet traffic into or out of a network. This can be used to avoid network monitoring or sniffers, or bypass badly configured routers on the Internet. Note: You might also need to change the settings in other programs (like your web browser) in order to circumvent these filters.
