I have developed a VPN application with PacketTunnelProvider that connects to the OpenVPN server. It works perfectly fine. Now I have the following requirements.
- The user should be able to block a particular domain, such as www.facebook.com while staying connected to the VPN server.
For the above requirement, I need to capture the DNS request for facebook.com and see if it is in the block list provided by the user and block the DNS request.
I don't have to have multiple network extensions, I need to handle it from one Packettunnel provider that is already handling OpenVPN connection.
Can anyone help me here with this use case?
