The Design and Implementation of laffer1

 I had a problem with a server at work recently.  I used to use a hint from the macosxhints site to reverse ssh into my home mac.  However, I can't do that anymore because my mac is behind NAT.  What I needed was a way to connect to the mac at work which was behind a firewall (but not nat).  I had another machine running FreeBSD with SSH open.  

Solution:

Connect to machine one

ssh -C -4 -L 5901:127.0.0.1:5900 remotehostyouwant  Connect to work mac: 
ssh -C -4 -L 5900:127.0.0.1:5900 macatwork
