Hey Matt thanks for your reply. We constantly are sending messages back and forth from container to the provider and back. We have a running daemon that updates the UI with statistics, setting updates and network changes relevant to the user. We currently use SendMessageToExtension but its not ideal. I would much rather use XPC (NEMachServices), is this available on iOS? Our current macOS uses the Network Extension ( we will send to the App Store ) and would like to use XPC there also, is it possible with a sandboxed app?

No I receive null keys either way when hotspot helper gets activated in the background.

Matt, Im not sure why this is solved? I think a user should receive launch keys stating the helper wakes up the app. We get zero indication regardless if its a backgrounded process or a cold launch.

I'm encountering issues with using includeAllNetworks where NECP is denying adapter usage, among other problems. Are you aware of any specific reasons why setting default routes wouldn't direct traffic through the tunnel? Additionally, it seems that with includeAllNetworks, enforcing routes may not function as expected. Any insights or guidance you could provide on these matters would be greatly appreciated.

One of the biggest issues is that if you set includeAllNetworks , then attempt to bind to a cellular adapter via sockets OR use NWConnection and prohibit WiFi and require Cellular but you are on a WiFi network, NECP will deny the cellular use. When binding, it will succeed, but then route traffic over the default route anyway. Ideally, with includeAllNetworks, we would like to bind to each adapter and decide when each should be used. Is this expected with includeAllNetworks?

Yes, inside of the PacketTunnel Provider we use sockets to bind to an interface. This is used for faster failover, avoiding bad networks and aggregating for speed. With include all networks set to on, we can successfully bind to pdp_ip0 when en0 is active however , attempting to use that socket it gets routed through the default en0 interface. You can test it out when binding to pdp_ip0 with include all networks on, sending a ping to ifconfig and it will return with the default interfaces IP.

App ([BUNDLEID) is using NEHotspotHelper API and it's unresponsive to API's evaluate command. The API gives 45 seconds to 3rd party apps to respond, and then it launches WebSheet to allow user to interact with the portal. // Captive state machine started 2024-09-20 19:39:35.722906-0700 0xb2a Default 0x0 50 0 configd: (CaptiveNetworkSupport) [com.apple.captive:Controller] en0: SSID 'Costco Member Wifi' setting interface rank Never (no cache entry) // Captive evaluation started 2024-09-20 19:39:35.729462-0700 0xb2a Default 0x0 50 0 configd: (CaptiveNetworkSupport) [com.apple.captive:Controller] CNPluginHandler en0: Evaluating 2024-09-20 19:39:35.803915-0700 0xb2a Default 0x0 50 0 configd: (CaptiveNetworkSupport) [com.apple.captive:Controller] en0: Probing 'Costco Member Wifi' // Builtin completed its evaluation 2024-09-20 19:39:36.666749-0700 0xb2a Default 0x0 50 0 configd: (CaptiveNetworkSupport) [com.apple.captive:Controller] en0: Redirect detected on 'Costco Member Wifi' // app acknowledged the evaluate command delivery 2024-09-20 19:39:36.669560-0700 0xb2a Default 0x0 50 0 configd: (CaptiveNetworkSupport) [com.apple.captive:Controller] [com.xfinity.digitalhome] acknowledged the command delivery // evaluation timed out after 45 seconds 2024-09-20 19:40:20.807153-0700 0xb2a Default 0x0 50 0 configd: (CaptiveNetworkSupport) [com.apple.captive:Controller] CNPluginHandler en0: Authenticating (BUILTIN)
