AirPort Extreme, firmware 7.5.2 and iVPN
Suddenly my VPN connection to my iMac stopped working. Using iVPN and L2TP. After some tests and thinking I thought the problem must have to do with firmware update of my AirPort Extreme to 7.5.2. I don't remember what version I ran before the update. I guess 7.5.1 since I always do update if there are any. Anyway. One last desperate thing I did was to downgrade the firmware via AirPort Utility to 7.4.2. 7.4.2 is the 2nd latest version available in AirPort Utility. Now the iVPN connects again. I couldn't see anything in the logs in my AE when running 7.5.2 pointing to port forwarding issues.
