Pi-hole 无法连接到 Unbound DNS

Pi-hole 无法连接到 Unbound DNS

我面临的问题: Pi-hole 无法连接到 Unbound DNS

我希望发生什么

我想使用 Pi-hole 过滤我的网络,并使用 Encrypted Unbound 作为 DNS 以保护隐私。我已经设置了 Pi-hole 和 Unbound,它们似乎都可以正常工作。当我连接到 Quad9 时,Pi-hole 可以工作,而 Unbound 可以挖掘网站(所以我假设它可以工作)。问题是,当我开始将两者结合起来时,它就停止工作了。当我使用 Unbound 作为 Pi-hole 中唯一的 DNS 时,我无法连接到任何网站。

    # be configured to limit DNS messages sent over UDP to a size that will not
    # trigger fragmentation on typical network links. DNS servers can switch
    # from UDP to TCP when a DNS response is too big to fit in this limited

自从安装Pi-hole以来我做了哪些改变:

我将 DNS 服务器更改为127.0.0.1#5335使用 Unbound DNS Pi-hole DNS 服务器

但在启用其他 DNS 解析器(Quad9)之前我无法加载任何网站

有办法解决此问题吗?谢谢

在默认网络模式(bridge)下,容器的网络命名空间与主机的网络命名空间隔离,环回地址在一个容器上下文中的含义与在主机上下文中的含义不同。

您应该将 pihole 指向主机系统使用的 IP 地址之一,例如物理 NIC 上的 IP 地址或为 Docker 网络创建的桥上的 IP 地址。
