Bug Description

example.com dns = 207.55.123.1
hk.example.com dns = 8.12.11.7
frpc设置http 880 自定义域 hk.example.com
访问hk.example.com:880/api 正常但"X-Forwarded-For" =[]string len: 1, cap: 1, ["207.55.123.1 "]
子域名和主域名dns不相同应该配置什么就是什么主域名完全不相关也把ip传过来了

配置会报错 start error: '.' and '*' are not supported in subdomain

~~使用宝塔反代127.0.0.1:880直接报错404都不带解析过去的第一次用这个 (ngix问题)~~
proxyproto 配置比如go的可以放文档里
tcp测试了没问题 http我是走的ngix反代 XRIP 也是可以获取到的
走反代的情况会对比host host必须设置proxy_host 这个强校验是否可以关掉?

ngrok随手就配好了这个真的不要太复杂奇怪的姿势太多了点
