Hi, 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 "example.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?
