检查nginx设置，传递真实ip

  location /
  {
    proxy_pass http://127.0.0.1:1080/;  # 你的地址
    proxy_redirect / /;
    proxy_cookie_path / /;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }

  location /dns-query
  {
    proxy_pass http://127.0.0.1:1080;  # 你的地址
    proxy_bind 127.0.0.1;
    proxy_set_header        X-Real-IP          $remote_addr;
    proxy_set_header        X-Forwarded-For    $proxy_add_x_forwarded_for;
  }
}

进入docker，编辑配置文件

sudo docker exec -it adguardhome /bin/bash
cd /opt/adguard/config
vi AdGuardHome.yaml

在配置文件的trusted_proxies中添加

  trusted_proxies:
  - 127.0.0.0/8
  - ::1/128
  - 172.17.0.0/24  # 根据实际情况更改
