title: How to create a GRE tunnel on Mac OSX Lion?
body: <p>i'm trying to find a way to create a GRE Tunnel on osx lion, i'm able to create such tunnels in almost every os, including: openbsd/freebsd, linux and cisco IOS.</p>
  
  <p>I'm very surprised that this subject is not discussed in any related osx threads over knowledge sources, ie. google, forums and QA sites.</p>
  
  <p>I found only a couple questions on forums without answer.</p>
