I discovered the issue here: https://discussions.apple.com/thread/5467273?start=135&tstart=0 However, I am running Mavericks (10.9.2) so the issue apparently Apple has not resolved...no clear cut answer either. I am very angry for having spent significant amount of time trying to resolve VPN issue that was supposedly patched with 10.9.1 version. Please can someone provide a clear working solution? I don't have that file that most folks have removed. I am using VPN L2TP over IPsec as a client on my MacBook Pro.
