Hey René,

I figured it out; it was a bug in the test suite, relying on default
Linux values, instead of explicitly setting them. It was introduced
here:

https://git.zx2c4.com/WireGuard/diff/src/tests/netns.sh?id=af2435d180ebb5a3d89b21eb9118d1c643f03f95

And I've fixed it here:

Thanks for sending all the info!

Regards,
Jason
