Dear all,

I set up Wireguard on a Raspberry Pi 3b and on my Android 9 phone with LOS. I'm using the latest Wireguard App v0.0.20191018 from Play Store.

Full tunnel connection works fine and I didn't exclude an app within wg options. I can see upload and download traffic on my Raspberry Pi from all apps but not from Play Store. When I browse in Play Store and read description of apps traffic is shown. But not when I download something. After that I checked with tcpdump on Raspberry side. Shortly after initiating a download there is a little bit traffic but while downloading apps with 100 MByte or more no traffic is going through my tunnel.

Did someone have such a strange behaviour before and knows how to fix that?

Besides that how can I troubleshoot that?

Best regards

Tobias
