Master NPS: Fast, Secure Intranet Penetration and Remote Access Guide

NPS Overview

NPS is an open‑source, lightweight, high‑performance intranet penetration proxy server that supports multiple protocols (TCP, UDP, HTTP/HTTPS, SOCKS5) and offers a robust web management console. It enables remote access, debugging, and service publishing for devices behind NAT without requiring a public IP.

Key Features

Protocol Support : TCP/UDP forwarding, HTTP/HTTPS conversion with easy certificate management, SOCKS5 proxy and P2P penetration.

Cross‑Platform Compatibility : Runs on Linux, Windows, macOS, and Synology NAS; can be installed as a system service.

Web Management UI : Visual client/server creation without editing config files, real‑time traffic, system status, and bandwidth monitoring.

Extensible Functions : Built‑in caching, compression, encryption, traffic and bandwidth limits, custom 404 pages, URL routing, and wildcard DNS.

Multi‑User Support : Allows multiple users to register and share a single server instance.

Installation Guide

1. Download the appropriate server and client binaries from the GitHub Releases page for your operating system.

2. Install Server

Linux/macOS :

sudo ./nps install
sudo nps start

Windows (run as Administrator):

nps.exe install
nps.exe start

Default ports after installation:

80/443 – host mode default ports

8080 – web management UI

8024 – server‑client communication

3. Install Client

Create a new client in the web UI to obtain the startup command.

Linux :

sudo ./npc -config=npc.conf
sudo ./npc -serviceinstall
sudo systemctl start npc

Windows : replace ./npc with npc.exe and run the commands in cmd.

4. Configure Penetration Service

Log into the web management console at SERVER_IP:8080, add a service (e.g., TCP or HTTP proxy), and enable the desired port forwarding to achieve intranet penetration.

Conclusion

NPS combines high performance with ease of use, making it a valuable tool for operations engineers and developers who need reliable remote debugging, device access, or public exposure of internal services without complex network configurations.
