我在使用 Android 客户端连接 OpenVPN 服务器时遇到问题。
我刚刚使用提供的脚本安装了它 https://github.com/Nyr/openvpn-install（openvpn-安装.sh）；
我正在运行 Ubuntu Server 16.04。
基本上，我可以使用任何 Android OpenVPN 客户端（我尝试了几个）进行连接而不会出现错误，但没有互联网连接。Android 版本 5.1。在我的 Ubuntu 笔记本电脑上使用 openvpn-networkmanager 插件，一切都很好（包括互联网导航）- 通过 3G 热点连接。
/etc/openvpn/server.conf这是Ubuntu服务器上的内容：
port 1194
proto udp
dev tun
sndbuf 0
rcvbuf 0
ca ca.crt
cert server.crt
key server.key
dh dh.pem
auth SHA512
tls-auth ta.key 0
topology subnet
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 192.168.1.1"
keepalive 10 120
cipher AES-256-CBC
comp-lzo
user nobody
group nogroup
persist-key
persist-tun
status openvpn-status.log
verb 3
crl-verify crl.pem
这是在 Android 上启动 VPN 客户端后立即出现的 JOURNALCTL 日志 - 然后我的笔记本电脑 (HP) 上的 VPN 也启动了：
