Breaks internet connection with Shadowrocket (iOS VPN app)

ViRb3 commented 2 years ago

Steps to reproduce

Install Shadowrocket iOS app on a M1 Mac
Connect to a VPN server using the app

Expected behavior

Internet works.

Actual behavior

Internet does not work unless you disable AdGuard.

ping still works, but TCP seem to fail. For example, ssh errors, and HTTP requests result in:

$ curl -v google.com
*   Trying 240.0.0.9:80...
* Connected to google.com (240.0.0.9) port 80 (#0)
> GET / HTTP/1.1
> Host: google.com
> User-Agent: curl/7.77.0
> Accept: */*
>
* Empty reply from server
* Closing connection 0
curl: (52) Empty reply from server

I suspect this may be a more general issue with iOS VPN apps in general, but I have not found a good way to test that.

Your environment

macOS 12.0.1 MacBook Pro M1 Max AdGuard 2.6.1.1051 Shadowrocket 2.1.92 (1451)

Sorry for the late reply.

The thing is that at the moment there is no support for compatibility with iOS VPN applications. We will work in this direction in the near future.

As a workaround, you can try to configure upstream proxy in the AdGuard advanced settings section provided that the VPN can operate in proxy mode.
