OpenVPN接続を作成しようとしています。 Windowsを使用している同僚は、すべてを設定する自動解凍実行ファイルを受け取りましたが、私は自分の.ovpn構成から主要なファイルを復元できました。
.opvn 言う:
dev tun
persist-tun
persist-key
cipher AES-256-CBC
auth SHA1
tls-client
client
resolv-retry infinite
remote aaa.bbb.ccc.ddd 1194 udp
verify-x509-name "Bad_VPN" name
auth-user-pass
pkcs12 SomeKey.p12
tls-auth SomeKey-tls.key 1
ns-cert-type server
comp-lzo adaptive
パスワードが十分であれば、接続が開始され、システムにpingを送信できます。ただし、VPN を起動してすぐにpingVPN を起動すると、実行が続行されます。
- 約1分後、もうping応答はありません（no seq> 57）。
- 約1分後、最後のping応答（seq = 118の応答）と「tun0」が無効になったというメッセージが表示されました。
また、VPNが稼働している場合は、接続されたネットワークにのみpingを送信できます。
VPNが起動すると、ip route以下が表示されます。
default via 192.168.30.1 dev tun0 proto static metric 50
default via xxx.143.182.1 dev wlp4s0 proto static metric 600
xxx.0.136.31 via xxx.143.182.1 dev wlp4s0 proto dhcp metric 600

192.168.30.0/24 dev tun0 proto kernel scope link src 192.168.30.3 metric 50
比較にVPNを使用しない場合：
default via xxx.143.182.1 dev wlp4s0 proto static metric 600
xxx.0.136.31 via xxx.143.182.1 dev wlp4s0 proto dhcp metric 600
xxx.143.182.0/23 dev wlp4s0 proto kernel scope link src xxx.143.182.197 metric 600
（xxx.*.*.*私がよく使うネットワークで、aaa.bbb.ccc.dddVPNゲートウェイです。）

NM GUIを使用して自動ルーティングを削除しようとしましたが、この方法で機能する設定を取得できませんでした。また、いくつかのバリエーションを試してみましたが、ip route del default via 192.168.30.1 dev tun0エラーメッセージが表示されなくてもパスは持続します。
どんなアイデアがありますか（Windows VMを起動する以外に...）？
(K) Ubuntu 16.04 実行
修正する：いいね、嘘をついた：）私もドッカーを持っていて、出力docker0から削除して... NM GUIを使って切断するのがトリックのようです。 2000万回実行しましたが、いくつかのパケットのみが失われました（10/1261）。しかし、OpenVPNとdockerがお互いに好きではないというヒントは見つかりません。ip routedocker0
