Here I am filtering based on connection only (i.e NEFilterDataProvider). I am reading through all of the data in all of the outbound / inbound flows.

One more thing, If I use another app to send the messages by using unixgram domain sockets then immediately i am getting "no buffer space" error even without network extension. Is there any way to increase the network load in mac?

Even it is building properly on Sonona Intel with Xcode 15.4. But failed to build on Sonoma Silicon. What would be the possible reason? Pls help.

My understanding was wrong. System Settings UI navigation to enable the network extension is little bit different in Sequoia from previous MacOS. My Network extension is working now.
