VPN 2.0

Lightweight multithreaded proxy over TCP
Pure C++ implementation. Built for speed and minimalism.

---

Overview

VPN 2.0 is a TCP-level proxy that mimics basic VPN behavior through simple forwarding.
The client connects to the proxy server and requests a target destination. The server resolves the destination and forwards traffic accordingly.

No encryption. No external dependencies. Just sockets and threads.

---

Features

• Multithreaded client handling
• IP + port forwarding with destination parsing
• Platform support for Windows & Linux
• Simple HTTP tunneling (default: httpbin.org)
• Flag structure for chaining/multi-routing (planned)

---

Usage

Build

Windows (MSVC)

cl main.cpp vpn_client.cpp /I util ws2_32.lib
cl server.cpp /I util ws2_32.lib

Linux (g++)

g++ main.cpp vpn_client.cpp -o client -pthread
g++ server.cpp -o server -pthread

Requires C++17 or later

---

Run

Start the server:

./server

Connect with client:

./client -ipv4 127.0.0.1 -p 5000

---

Flags

Flag	Description
-ipv4	Proxy server IP (default: 127.0.0.1)
-p	Port to connect to (default: 5000)
-pass	Optional password (unused for now)
-multi	Enables multi-routing (WIP)

---

Example

./client -ipv4 127.0.0.1 -p 5000

Prints your public IP by routing a GET /ip request through the proxy.

---

Notes

• Server listens on port 5000 by default
• Client requests are parsed line-by-line: host:port followed by HTTP payload
• Modular design with Flags, Client, and server logic split
