已连接到 OpenVPN，但没有互联网连接，也无客户端到客户端的连接

我刚刚在 Raspberry pi v3 上安装了以下设置，其 IP 为 192.168.1.2：

  1. 首先，我安装了 PiHole
  2. 然后我安装了 PiVPN
  3. 做了一个调整/etc/openvpn/server.conf：我注释掉了现有的dhcp-options并添加了push "dhcp-option DNS 192.168.1.2"，192.168.1.2PiHole_IP 在哪里
  4. 我为我的手机创建了一个证书

我能够从手机连接到 VPN，但如果我尝试打开任何网站，我都不会收到任何响应。如果我尝试在 LAN 上查找任何客户端，我也不会收到任何响应。

以下是从我手机的开放式 VPN 应用程序中获取的日志：

此外，我可以看到 PiHole 正在从 IP 10.0.8.2 接收请求，这些请求未被阻止。我不确定从哪里开始进行故障排除，并期待任何提示和指导 :-)

除了删除默认的 Google DNS 服务器和推“dhcp 选项 DNS 192.168.1.2”在服务器配置文件，您已经完成了，请执行以下操作：

  • 转到/etc/dnsmasq.d并创建一个新文件，例如自定义配置文件（sudo nano custom.conf），内容如下：

    listen-address=127.0.0.1, 192.168.1.2, 10.8.0.1

    在哪里192.168.1.2是你的 Pi-hole DNS 地址，10.8.0.1是 PiVPN 网关。

    这确保了如果 Pi-hole 更新，其他配置文件的更改不会被覆盖。

  • 运行以下命令重启 OpenVPN 服务

    sudo service openvpn restart

现在，当您从客户端连接到 PiVPN 时，您应该能够访问互联网，并且 Pi-hole 应该会过滤所有广告。
