Realistically we only have 5 minutes so get with me after if something needs a bit more clarification

Grab remote services down to your local machine

ex: You're SSHd to a host with a database and you want to run your cool database app against the remote servers database

ssh -L local_ip:local_port:destination_ip:destination_port example.com

ssh -L 0.0.0.0:5433:127.0.0.1:5432 example.com
ssh -L 1433:1.2.3.4:1433 example.com
ssh -L 192.168.1.37:8443:127.0.0.1:443 example.com

Shovel local services to your remote machines

ex: You deploy a network dropbox and you want to ensure a remote host can ssh into the protected network

ssh -R local_ip:local_port:destination_ip:destination_port example.com

ssh -R 22:127.0.0.1:42022 example.com
ssh -R 1.2.3.4:443:0.0.0.0:443 example.com

Create dynamic connections initiated from the remote host

You want to watch BBC4 but you dont live in the UK

ssh –D local_port

ssh -D 8080
