Hello @ahasenack,
This is an interesting thread.
I have the same needs (connecting 2 sites by Wireguard, or another solution) but the main problem is that on one I don’t have control of the Router so my devices are behind a NAT. This means that there is no Public IP on one side, neither port forwarding is possible.
Is there a workaround for creating a site-2-site VPN with Wireguard in a similar environment?
To provide more content, I have made a test but it seems working only in 1 direction (e.g. site behind a NAT can access to the Network of the other side, but not vice-versa).
Regards,
