I tried the RPis with another connection and they worked briefly but
most of the time they don't respond. I configured another laptop under
the same other network connection and everything works seamlessly. It
seems that the RPis just don't like WireGuard. I might have some network
misconfiguration on them but I really can't figure it out.
