iOS Client is not working to use VPN only for DNS queries

[tugsjargal]

Dear Guys,

I've implemented your great API for iOS app. When we install .ovpn file via OpenVPN Connect, DNS queries are working perfect and our Android version is working as expected.

But I implemented openvpn3 to our iOS app. This is not working. I think DNS settings are not applied to iPhone device settings. I am using latest version of openvpn3.

On my server.conf:

;push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 10.8.0.1"

I have set NEPacketTunnelNetworkSettings object as provided from openvpn Server in NEPacketTunnelProvider class. But all traffic transfers iPhone -> EndPoint. I would get only DNS traffics transferred via VPN tunnel.

Do you have any idea ?

Thanks.
