createTCPConnection not establishing tunnel in ClientTunnel

[jorgeavelar98]

Hello @yarshure @networkextension ,

Ive been working on a MacOS per-app vpn client very similar to yours. I seemed to have an issue where the PacketTunnelProvider extension would stop running when ever it would hit the first line in the "observeValue" function in the ClientTunnel class. I noticed that you were having a similar issue and changed a few lines within the ClientTunnel class. I did the same and the app extension no longer stops.

However, the ClientTunnel still seems to fail to establish the tunnel to the server. After I call
connection = provider.createdTCPConnection(parameters)
connection state switched to "connecting" but then switches to "waiting" within the "observeValue" function, meaning that it failed to create the TCP connection. I downloaded and ran your example project and it seems to have the same issue.

So I am wondering if you could help me fix this issue. In your code, right above the line of code you changed, you wrote:
//stop reason = Simultaneous accesses to 0x1037010e8, but modification requires exclusive access
What does "modification requires exclusive access" mean. Is this the issue?

Thanks!

So I run the server on port 8889 and I give my client my computer's IP address along with port 8889 as the server address. (ex: 10.30.56.101:8889). This server address is included in a configuration profile I then install into the Mac and loaded by an NETunnelProviderManager in the host app.

Note: I run the server and per app vpn client on the same Mac computer.

Maybe you will use two Mac ,or one iOS and one Mac to test AppProxy VPN logic. Another after client app extension started, you should attach the process, and observe process behavior . Last winter, I had run AppProxy client on iOS device, and send flow data to http/socks5/Shadowsocks proxy server, work fine. 发自我的 iPhone

I see, thanks. The one I am having trouble with is the PacketTunnelProvider Extension though. Did that one work the last time you ran it?
