Forward Multiple Ports Over SSH

I sometimes find myself doing web app development on another machine via an SSH connection. If I have the server running on port 3000, then I like to use SSHā€™s port forwarding feature so that I can access localhost:3000 on my physical machine.

$ ssh dev@server.com -L 3000:localhost:3000

What if I have two different servers running? Iā€™d like to port forward both of them ā€” that way I can access both.

SSH allows you to forward as many ports as you need. The trick is to specify a -L for each.

$ ssh dev@server.com -L 3000:localhost:3000 -L 9009:localhost:9009
