我对 Ubuntu/Linux 还比较陌生，主要按照在线指南来实现我想要的功能。
不过我认为我目前弄乱了我的 /etc/network/interfaces
当我重新启动机器时，我必须输入“sudo iptables -P INPUT ACCEPT && sudo iptables -F INPUT && sudo iptables -P OUTPUT ACCEPT && sudo iptables -F OUTPUT”，这一行是在我安装 NordVPN 后使用的，他们的一位代理将这一行提供给我，以使机器与 NordVPN 一起工作。
此后，我已经卸载了 NordVPN，但如果我想通过 SSH 进入机器，重新启动机器时仍然必须输入该评论。
我的机器上也运行着 Plex，它显示错误“发出 curl_easy_perform(handle): 6 时出错”，我认为这与 DNS 有关。

更复杂的是，我有两个与 DNS 相关的 Docker 容器；
我的主板也有 2 个（技术上是 3 个，但第三个是 IPMI，似乎不受任何影响）网络端口（192.168.1.160 和 161）
我很困惑，不知道该如何解决我的问题，如果我禁用任何 Dockers，我仍然会遇到同样的问题，如能得到任何帮助我将不胜感激。
理想情况下，我希望我的路由器（192.168.1.1）指向 Lancahe（192.168.1.160），它将缓存任何 steam 等游戏以供将来本地下载，它将指向 Piehole（192.168.1.161）以停止宣传 DNS 查询。
*Pihole 有 30 多个与 plex 关联的白名单域名
我还为 P2P 链接安装了 10gbe 卡，但由于这让事情变得更加复杂，所以我禁用了它，现在我想在没有它的情况下让它工作。
