测试正常的示例

frpc.ini

[common]

server_addr = x.x.x.x
server_port = 7000
protocol = kcp
token = testpasswd


[3389]

type = tcp

local_ip = 127.0.0.1

local_port = 3389

remote_port = 33891

[3389UDP]

type = udp

local_ip = 127.0.0.1

local_port = 3389

remote_port = 33892

frps.ini

[common]
bind_port = 7000
kcp_bind_port = 7000
bind_udp_port = 7001
token = testpasswd

碰到错误的几个想法

1. 先看看端口是否打开

2. 从最简单的开始配置，慢慢排查问题
