Hi all,

I'm having a weird one here, I'm trying to setup my own service using tunnel.dll from Rust. When I read the config file from Rust and send it to the tunnel.dll I properly see that's it's parsing the config, starting all the workers and attempting to connect, but it never manages to get the handshake properly.

On the same machine, the AmneziaVPN Windows client works and creates it's tunnel successfully, with the exact same config file. I'm a bit at a loss here, I'm sure my keys are correct, time is set properly, etc...

Issue is the same whether I use the tunnel.dll from building this repo, alongside wintun.dll 0.14 from the web or I replace them with the ones from the AmneziaVPN install.

What could be wrong? The virtual interface gets properly named & setup, routes are properly setup within Windows.

Regards,
Adrian.
