frp 0.33.0
服务端环境centos 7 (有公网ip)
远程客户端环境centos 7 (无公网ip)
本地客户端环境win10 (无公网ip)
服务端已配置 udp
远程客户端配置

[webdav2] 
type = xtcp                        
sk = 123456                        
local_ip = 127.0.0.1               
local_port = 9800

本地客户端配置

[p2p_webdav_visitor]
type = xtcp
role = visitor
server_name = webdav2
sk = 123456
bind_addr = 127.0.0.1
bind_port = 9800

远程客户端debug日志

。
查看这一句
workConn(l[192.168.126.4:36732] r[1.192.35.170:6744])
126.4是远程客户端的dhcp地址，并不是公网ip。35.170是本地客户端的公网ip。
请问大神这是什么造成的，我应该怎么做。

使用xtcp建议访问者或客户端有公网IP

一个可能的解决方案，把远程客户端的frpc架设在主路由器上。我之前也是假设在机器上永远是timeout，后来假设在路由器上就可以穿透了，猜测是nat层级多了之后穿透的难度就增加了，你可以试试
