<p><font face="Verdana">Hi all,</font></p>
<p><font face="Verdana">I have setup Wireguard on a Gentoo box,
compiled it into the kernel using instructions on the wireguard
website. Got my mobile to connect using 4G to this box fine, so
I wanted to test further with a friend of mine who has a DD-wrt
installation on his router. Wireguard is integrated into the
DD-wrt build, we set it up, but the tunnel does not come up. On
the server I only see this:</font></p>

you have an idea?</font></p>
