请教公网出入口不同的NAT VPS，Nginx如何获取到真实访客IP
2024/06/09 20:05:37
求大佬们指点，{:3_49:}
买了个鸡仔云，打算穿透家里的小鸡出来做后端。
已经用frp穿透到28000端口，
已知入口IP为：1.2.3.4
通过curl 测试IP得值：4.3.2.1
应该是出入口IP不同？
通过指定hosts访问测试站点，但查看日志，获取到的IP全都是4.3.2.1
如果启用"proxy_protocol"则浏览器无法访问，就注释了。
{:2_32:}
openresty即nginx加功能版，http配置里设置了
server配置如下
反代的location如下
