Use frp for intranet penetration
1.frp concept
frp is mainly composed of a client (frpc) and a server (frps). The server is usually deployed on a machine with a public IP, and the client is usually deployed on a machine where the intranet service that needs to be penetrated is located.
Since intranet services do not have public IP addresses, they cannot be accessed by other users outside the LAN.
Users access the frps on the server side, and frp is responsible for routing the request to the corresponding intranet machine based on the requested port or other information to achieve communication.
2. Server-side construction
Just choose the installation package that suits your server and download it:
Since my server is Linux, I choose this:
Use wget to download the installation package to the server, decompress it, and change the directory name to frp (for easy retrieval):
