当 eth0 启动时 Wireguard 不工作

设置

• 路由器作为我网络上的 Wireguard 服务器
• 树莓派
  • 操作系统：Raspbian Buster
  • 通过 wifi 连接到移动热点（接口 wlan0）
  • et0设置为静态IP，可以直接控制静态IP的设备，无需交换机或路由器
  • wg0 配置为连接到我的路由器上的服务器

问题

仅当我使用 禁用 eth0 时，wireguard 连接才有效ifconfig eth0 down。

我想做的事：

我需要在 Pi 上更新并测试软件的更新。该软件使用连接在 eth0 上的设备，因此我需要 eth0 处于活动状态。

我尝试过的

除了谷歌之外，什么也没有，但我找不到任何适合我的具体问题的东西。

我怀疑我需要更改路由表，但我不确定谁和我不想中断 wifi 连接。
