small question about explanation

[hetzbh]

In your instructions connecting both Raspberry Pi A & B, shouldn't Raspberry Pi A have rpia_public.key and Pi B have rpib_public.key ?

[adrianmihalko]

No, On Raspberry Pi A you must use Raspberry Pi B's key (rpib_public.key) and vice versa.

Then if you connect with Raspberry Pi A to Raspberry Pi B: Raspberry Pi B can pair/sign his (rpib_public.key from the config on Rpi A) with his private key. And vice versa too.

Oh, you're right, but what happens when I want to connect between >2 Pi's? (5, for example)

Each WireGuard interface may have multiple peers:

       [Interface]
       PrivateKey = yAnz5TF+lXXJte14tji3zlMNq+hd2rYUIgJBgB3fBmk=
       ListenPort = 51820

       [Peer]
       PublicKey = rpib_1.publickey
       Endpoint = 192.95.5.67:1234
       AllowedIPs = 10.192.122.3/32, 10.192.124.1/24

       [Peer]
       PublicKey = rpic.publickey
       Endpoint = [2607:5300:60:6b0::c05f:543]:2468
       AllowedIPs = 10.192.122.4/32, 192.168.0.0/16

       [Peer]
       PublicKey = rpid.publickey
       Endpoint = test.wireguard.io:18981
       AllowedIPs = 10.10.10.230/32

...etc. Feel free to ask at: #Wireguard

Thanks for the explanation ;)

No problem, use it, it's a great tool!
