WireGuard VPN

WireGuard Server

WireGuard Server: Debian

WireGuard Client

WireGuard Client: Raspberry Pi OS

Exemple de configuració

Al servidor:

sudo wg show wg0

Server:~$ sudo wg show wg0

Arxiu /etc/wireguard/wg0.conf :

# define the WireGuard service
[Interface]

# contents of file wg-private.key that was recently created
PrivateKey = SD***************************************1Q=

# UDP service port; 51820 is a common choice for WireGuard
ListenPort = 51820

# define the remote WireGuard interface (client)
[Peer]

# contents of file wg-public.key on the WireGuard client
PublicKey = EG***************************************yI=

# the IP address of the client on the WireGuard network
AllowedIPs = 10.0.2.2/32

# define the remote WireGuard interface (client)
[Peer]

# contents of file wg-public.key on the WireGuard client
PublicKey = Pw***************************************gQ=

# the IP address of the client on the WireGuard network
AllowedIPs = 10.0.2.5/32

Al client:

sudo cat /etc/wireguard/wg0.conf

Client:~$ sudo cat /etc/wireguard/wg0.conf

Per a que hi hagi visibilitat entre diferents clients de la VPN cal comentar l'exclusivitat de connexió al servidor (10.0.2.1/32) i permetre que altres hi puguin accedir (0.0.0.0/0). I per a mantenir la persistència del túnel s'ha afegit PersistentKeepalive:

# AllowedIPs = 10.0.2.1/32
AllowedIPs = 0.0.0.0/0, ::/0

PersistentKeepalive = 25
