一个模拟示例

下载windows版本的frfps

需要准备的测试设备

1. 一台frp服务器
2. 一台frp客户端PC
3. sscom5.exe测试软件开2个，来模拟野外的设备和本地连接野外设备的软件。

原理

frp服务器搭建了一条中转的桥梁，frp的客户端在本地做好端口映射后，本地的设备软件就可以连接到野外的设备。

拓扑图

frps端信息

公网IP: 134.xxx.xxx.xxx
在路由中打开7001~7002端口，用于野外设备上传数据。
配置frps.ini文件
主要参数：
服务器端口：7000
监控面板端口：7500

[common]
# A literal address or host name for IPv6 must be enclosed
# in square brackets, as in "[::1]:80", "[ipv6-host]:http" or "[ipv6-host%zone]:80"
bind_addr = 0.0.0.0
bind_port = 7000

# udp port to help make udp hole to penetrate nat
bind_udp_port = 7001

# udp port used for kcp protocol, it can be same with 'bind_port'
# if not set, kcp is disabled in frps
kcp_bind_port = 7000

# set dashboard_addr and dashboard_port to view dashboard of frps
# dashboard_addr's default value is same with bind_addr
# dashboard is available only
