I am seeing this behaviour also with the FilterPacketProvider. In the simple example at the bottom, we allow every packet flowing. With this extension enabled and about 15 Mbit/s receiving and 4 Mbit/s sending the connections in the browser timeout. This is more frequent with video conferencing tools like Meet and Teams, which are UDP based and a lot of traffic is generated Is there any news regarding the tickets? We are facing a lot of trouble with clients that have a contentFilter installed like for example some enterprise anti malware and firewalls agent like Cortex, where they keeps disconnecting from the video conference import NetworkExtension import os.log class FilterPacketProvider: NEFilterPacketProvider { static let log = OSLog(subsystem: "com.example.apple-...", category: "PacketProvider") private let log: OSLog override init() { self.log = Self.log os_log(.info, log: self.log, "FilterPacketProvider: init") super.init() } override func startFilter(completionHandler: @escaping (Error?) -> Void) { os_log(.info, log: self.log, "FilterPacketProvider: startFilter") self.packetHandler = self.handlePacketwithContext; completionHandler(nil) } override func stopFilter(with reason: NEProviderStopReason, completionHandler: @escaping () -> Void) { os_log(.info, log: self.log, "FilterPacketProvider: stopFilter") completionHandler() } private func handlePacketwithContext(context: NEFilterPacketContext, interface: nw_interface_t, direction: NETrafficDirection, _ packetBytes: UnsafeRawPointer, packetLength: Int) -> NEFilterPacketProvider.Verdict { return Verdict.allow; } }
