Multiple server/local instances of wireguard

[Flerlato]

I'm trying to set up additional local Wireguard servers with different configuration to serve different purpose and use separated interfaces. So far, it doesn't matter what I do, the additional servers can never do handshake with the clients.

I'm pretty sure I've done everything exactly the same as I did for the primary server and the clients, so I'm trying to figure out how am I being so stupid that I cannot make the additional servers to work. If there something obvious besides wrong public keys that could be at play here?

Hopefully you didn't do everything exactly the same, as you will have conflicting subnets, ports, keys etc. xD Post configs?
