+# SSH Port Forwarding
+
+## Local port forwarding
+
+This sends the traffic to the host you're SSHing into, e.g. accessing a service on a remote server.
+
+```sh
+ssh -L <local-port>:localhost:<remote-port> <user>@<server>
+```
+
+Or to forward that port to a different host *through* the SSH server:
+
+```sh
+ssh -L localhost:<local-port>:<different-host>:<remote-port> <user>@<server>
+```
+
+## Remote port forwarding
+
+This send the traffic from the SSH server to your local machine, e.g. running a web server on your local machine and making it accessible from the server.
+
+```sh
+ssh -R <remote-port>:localhost:<local-port> <user>@<server>
+```
