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 dev vpnserver
[#] ip link set vpnserver up
[#] wg set vpnserver fwmark 51820
[#] ip -4 route add 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:
MTU:1420  Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:4 dropped:0 overruns:0 carrier:0
          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:

And finally the down command output:

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