We are currently trying to connect an iOS 10 – iPhone 6S Plus to a synology package called: VPNServer using the OpenVPN service.
Unfortunately we are unable to connect from an outside network (4G, Vodafone NL) to the VPN server using your OpenVPN Connect app on iOS. If we try to connect locally using this app from within the network, the connection works. We have investigated our firewall configuration and established we have the correct forwarding rules enabled. Also: we are able to connect from outside networks using an Android device running Android 6+. So we don’t understand what causes the iOS device to fail connection from an outside network.
