vaporsec to check point

hello, I noticed that folks had success with vaporsec on macosx. I am desperately trying to set this up and consistently failing. I am trying to get this to work with entrust certificate that has been exported in p12 format and have imported it via the vaporsec gui - still no connection - when I do connect, I am not able to get to anything behind the firewall. can someone please please help me out? thank you Naynesh
