I have a PPTP VPN running on Windows 10 which works fine with my iPad 1, Google Nexus phone and Windows 7 laptop. I now have an iPad Pro which connects fine to the VPN and I can see all the internal services, but flatly refuses to connect to anything outside the VPN (e.g. trying to connect Safari to google.com fails). This all works fine on all my other devices, including the iPad 1. Anyone got any thoughts? I've tried resetting the network settings.
