In this video, learn about the three types of SSH tunnels: local, remote, and dynamic.
- [Instructor] We can use SSH to create a simple tunnel.…We can see in the diagram the traffic…is received by an SSH client on one computer…on a proxy port…is then sent from that computer…to the target using SSH.…The SSH service on the destination computer…then connects to the target service locally…on the correct service port.…An SSH tunnel is created by using a special form of port…forwarding within the SSH tool.…
There are, in fact, three forms of SSH tunnel.…We can create a local port forwarding SSH tunnel,…which allows us to redirect a port on the server…to another port on the same server.…It's a local tunnel that doesn't leave the server.…We can create a remote port forwarding SSH tunnel,…in which we expose a service on our computer…that can be accessed using a port on a different computer.…This is how we expose internal network services…through a DMZ.…
Finally, we can do dynamic port forwarding in SSH.…Dynamic port forwarding is the third major method…of port redirection within SHH.…Whereas both local and remote port forwarding…
