This guide explains what NPS (Network Penetration Service) is, why it’s needed, its core advantages, and provides step‑by‑step instructions for deploying the server and client on Linux, Windows, or Docker, configuring TLS, managing tunnels, and troubleshooting common issues.
This guide introduces the open‑source nps tool, explains its all‑protocol compatibility, low‑resource footprint, and step‑by‑step deployment process for both server and client, enabling seamless cross‑network access for personal, development, and enterprise scenarios.
This article explains the role of NAT and NAPT tables in routing packets between private subnets and the public internet, details how internal network traversal and hole punching work, compares forward and reverse proxy mechanisms, and outlines practical scenarios and differences between these networking techniques.
This article introduces the open‑source NPS intranet penetration proxy, outlines its key features such as multi‑protocol support and a powerful web UI, and provides step‑by‑step installation and configuration instructions for Linux and Windows environments.
This article introduces several widely used intranet penetration and proxy tools—including nps, frp, EW, and ngrok—explaining their core principles, key features, configuration steps, and practical usage scenarios for accessing internal services such as RDP, SSH, HTTP, and file sharing from outside networks.
This article explains the limitations of existing intranet penetration tools, presents a custom SSH port‑mapping script, and provides a step‑by‑step tutorial on deploying FRP (frps and frpc), configuring tunnels, managing services with systemd, and verifying port forwarding through the FRP dashboard.
This guide explains how to use an idle Alibaba Cloud server, install Docker, deploy the NPS reverse‑proxy container, configure security groups and client settings, and finally enable remote access to a local development service through an internet‑exposed tunnel.
This guide explains what frp is, why it’s a strong reverse‑proxy choice, and provides step‑by‑step instructions—including configuration files, port opening, and domain setup—to expose internal web services through custom domains securely.
This guide explains the fundamentals of FRP, a reverse‑proxy tool for intranet penetration, and provides step‑by‑step instructions to deploy the FRPS server and FRPC client with Docker, configure ports, view logs, access the dashboard, expose local services, and troubleshoot common issues.
This guide introduces four popular intranet‑penetration tools—NPS/NPC, FRP, EW, and Ngrok—detailing their core principles, key features, installation steps, configuration files, and practical usage examples for exposing internal services such as web servers, SSH, RDP, and file sharing to the public internet.
This step‑by‑step tutorial explains how to install and configure Nginx for free, create a simple website, start the server, and use a free tunneling service to expose the site to the internet without paying for hosting or a domain.
This article explains why home networks use private 192.168.x.x addresses, how NAT devices translate private IPs to a single public IP, the detailed SNAT/DNAT processes, the role of ports in NAPT, and how these mechanisms enable inbound connections through techniques like NAT hole punching and intranet penetration.
This tutorial explains how to set up a Java SpringBoot service, install and configure the cpolar intranet‑penetration tool, create HTTP tunnels for local ports, test the public endpoints with Postman, reserve a fixed sub‑domain, and use cpolar's listener for request debugging.
This article explains the concepts of public and private IP addresses, NAT techniques, and the principle of intranet penetration, then demonstrates how to set up and analyze the open‑source FRP framework, including configuration files and core Go code for both server and client components.
This article introduces several widely used intranet penetration tools—including nps, frp, EW, and ngrok—explaining their core principles, key features, and step‑by‑step configuration commands for establishing secure tunnels, proxy services, and remote access to internal resources.
This technical guide reviews several popular intranet penetration and proxy tools—including nps, frp, EW, and ngrok—explaining their core principles, key features, installation steps, configuration examples, and advanced options such as encryption, compression, dashboards, and multi‑level port mapping.
