私は自分のopenvpnサーバとクライアントを動かそうとしています。私のサーバーは7セントマシーンで、私のクライアントはミントシルビアです。
私はdockerを使ってyoutubeでこのチュートリアルに従いました（ リンクドイツ語 ） これがdockerの手順です。
curl -fsSL https://get.docker.com/ | sh
systemctl start docker
systemctl status docker systemctl enable docker
docker volume create --name OVPN_DATA docker run -v OVPN_DATA:/etc/openvpn --rm kylemanna/openvpn ovpn_genconfig -u udp://vpn.servername.com - Hier IP oder Domain von eurem Server einfügen
docker run -v OVPN_DATA:/etc/openvpn --rm -it kylemanna/openvpn ovpn_initpki docker run -v OVPN_DATA:/etc/openvpn -d -p 1194:1194/udp --cap-add=NET_ADMIN kylemanna/openvpn
docker run -v OVPN_DATA:/etc/openvpn --rm -it kylemanna/openvpn easyrsa build-client-full Desktop nopass
docker run -v OVPN_DATA:/etc/openvpn --rm kylemanna/openvpn ovpn_getclient Desktop > Desktop.ovpn
端末（sudo openvpn --config file.ovpn）に接続してもうまくいくことがありますが、Webページが表示されるまでに5分ほどかかります。これが私の端末の出力です：
