Hello, had someone run wireguard?`I have read today about it and try to run it through the Tutorial https://emanuelduss.ch/2018/09/wireguard-vpn-road-warrior-setup/ So all is connected, all looks as it work. But someone is wrong cause the ping work not correct. ping: sendmsg: Der notwendige Schlüssel ist nicht verfügbar* ping: sendmsg: Der notwendige Schlüssel ist nicht verfügbar ping: sendmsg: Der notwendige Schlüssel ist nicht verfügbar ping: sendmsg: Der notwendige Schlüssel ist nicht verfügbar *The necessary key is not available ping 10.23.5.2 PING 10.23.5.2 (10.23.5.2) 56(84) bytes of data. ping: sendmsg: Destination address required ping: sendmsg: Destination address required ping: sendmsg: Destination address required ping: sendmsg: Destination address required ping: sendmsg: Destination address required So all commands which be in the tutorial are present. ip a l wg0, wg show okay wg show give not more information self when clients are connected. Have here someone idea? Is there a way to become more log information? Maybe a tutorial which is more for Arch? Thank you for help & Nice new year Silvio
