OK, I'm gonna see that.

Here's the startup:

# ./SERVER_WG_UP.sh 
Démarrage du SERVEUR VPN WireGuard
[#] ip link add vpnserver type wireguard
[#] wg setconf vpnserver /dev/fd/63
[#] ip address add 10.11.12.1/24 dev vpnserver
[#] ip link set vpnserver up
[#] wg set vpnserver fwmark 51820
[#] ip -4 route add 0.0.0.0/0 dev vpnserver table 51820
[#] ip -4 rule add not fwmark 51820 table 51820
[#] ip -4 rule add table main suppress_prefixlength 0
SERVEUR VPN WireGuard démarré

The ifconfig output:

vpnserver Link encap:UNSPEC  HWaddr
00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:10.11.12.1

          collisions:0 txqueuelen:1 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

The wg show vpnserver command output:

# wg show vpnserver
interface: vpnserver
  public key: …
  private key: (hidden)
  preshared key: (hidden)
  listening port: 1194
  fwmark: 0xca6c

peer: …
  allowed ips: 0.0.0.0/0


And finally the down command output:

# wg-quick down vpnserver
wg-quick: `vpnserver' is not a WireGuard interface
