frp内网穿透 - Tue, Mar 19, 2019
frp 是一个可用于内网穿透的高性能的反向代理应用,支持 tcp, udp 协议,为 http 和 https 应用协议提供了额外的能力,且尝试性支持了点对点穿透。
1. 架构
2. 代理结构
frps部署在服务端(局域网1),并能够对外网暴露端口。frpc部署在客户端(局域网2),但是不能对外暴露端口。
为了让局域网1能够访问局域网2的内部服务,所以需要将局域网2的服务代理到局域网1。这样,局域网1就像访问内网的一样访问局域网2。
代理成功之后,也可以将代理的端口在局域网1暴露到公网上,使得,公网能够访问局域网2。
3. 前提条件
- frps服务端必须能够暴露公网端口。
- frpc能够连接外网。
