我在docker中部署了flask应用，还启用了iptables。 关于日志中请求的源IP，有2个问题。
当我访问网站（通过计算机或手机）时，显示所有请求均来自日志中的“ 172.17.0.1”（这是docker网关IP地址）。
我找到了这个答案：why-i-get-the-gateway-ip-as-source-address-in-docker-bridge-networking。 这个问题的根本原因应该与他相同，但是他没有描述如何调试导致此问题的条目。
我尝试了几种方法来访问该网站：从计算机或手机的浏览器，wget，使用python脚本的http.get。所有这些都表明请求来自127.17.0.1。但是，我还发现很多请求不是来自127.17.0.1，这些请求不是我发送的，所以我很困惑。这些请求来自哪里，为什么不是127.17.0.1中的请求，以及使用了哪些方式？
从日志文件中附加了一些日志：
这些日志是我的要求：
