I have disabled remote configuration on my Airport Extreme but was out of town and needed to add a new port to the router and forward it to an internal machine, made me scratch my head a bit. After some googling I found information on setting up an SSH tunnel to assist with this.
Recently I was in search of some ways to speed up my SSH connections as I spend a lot of my days within the terminal. I came across this handy little gem which can help you connect faster to a server that you already have a connection to. There is a feature within OpenSSH called connection sharing and its really easy to enable, and requires no edits to the server.
I came across SSHMenu, and its is very handy if you have multiple machines that you connect into on a regular basis. Here is a screenshot of the program to give you an idea.
You can get more information on it over at their Official Site.
