We have a Mac running OS X 10.11.5 that can not connect to the internet when it's connected to the VPN (PPTP). Once it's connected, it can only connect to things on the local network that the VPN has joined to. For example when connected to VPN, the Mac can access things like our internal file sharing and Intranet sites, but can not go onto internet connected sites in Safari. We have checked "Send all traffic over VPN connection" in the VPN connection settings. In terminal we can ping "google.com" and "22.214.171.124" when connected to the VPN. No other Internet enables apps work either (e.g. Dropbox, OneDrive, Skype etc.) Any ideas?
