iPhone VPN and Cisco IOS

I had quite a bit of trouble getting this to work the other day.  After some googling I came across this thread over on 6200networks.com.  I had matched up the config he had listed just by chance because I was also enabling an L2L VPN.  However, I still couldn’t get it to work.  The trick was to change the IPSEC transform set to AES-256.  After that it was smooth sailing.  I posted a comment over there but he hasn’t approved it yet.

I’ve discovered ISAKMP profiles too.  Very cool!

  1. Simply changed the transform set to AES-256.  He posted a follow up on 6200 and it might have been more related to the ver of IOS I was running, oddly enough.

  2. For some reason it never get’s past
