WireGuard is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography.

It is currently deployed on our lovely Ubiquity EdgeRouter-PRO.

Client configuration

/etc/wireguard/fixme.conf:

[Interface]
PrivateKey = HAHAHAHAHAHA
Address = 192.168.131.2

[Peer]
Endpoint = 62.220.131.170:53
PublicKey = 4FVgHmPtsY7Rg7VlNrNC0x2RVFHlYJOh8ln7q77THxo=
AllowedIPs = 0.0.0.0/0, ::/0

Send your public key to User:Francois to get added.
