Thanks! That will solve our issues with that. Is there a way to extract source app for a packet with packet filter? I see there is a context, but I'm not sure what and how we can extract from it.

Thought that too, but I do not see any new flow when calling ping. Same as with raw sockets. EDIT: saw you wrote NEFilterPacketProvider. It is not possible using DataProvider? Also, in what way can I get packet type in PacketProvider?

Sorry, I forgot to mention that part - macOS
