GameLAN VPN - Virtual LAN Gaming Solution

📝 Project Overview

GameLAN VPN เป็น Windows Desktop Application ที่ทำหน้าที่เป็น Virtual Private Network สำหรับเล่นเกมส์ LAN ระหว่างผู้เล่นที่อยู่ต่างสถานที่กัน รองรับเกมส์ เช่น Warcraft III, Red Alert 2: Yuri's Revenge และเกมส์ LAN อื่นๆ

🏗️ System Architecture

Components

1. Client Application - WPF Desktop App สำหรับผู้เล่น
2. Server Hub - SignalR Server สำหรับจัดการ rooms และ relay packets
3. Virtual Network Adapter - จำลอง LAN network ผ่าน Internet

🚀 Getting Started

• .NET 8.0 SDK
• Visual Studio 2022
• Git

Installation Steps

1. Clone repository:

git clone https://github.com/yourusername/GameLANVPN.git
cd GameLANVPN

2. Build solution:

dotnet build

3. Run server:

cd src/Server/GameLANVPN.Server

4. Run client:

cd src/Client/GameLANVPN.UI
dotnet run

📋 Development Roadmap

Phase 1: Core Infrastructure ✅

• Project structure setup
• Basic networking interfaces
• SignalR Hub implementation
• UI framework

Phase 2: Network Implementation 🚧

• Virtual adapter integration
• Packet capture and injection
• NAT traversal (UDP hole punching)
• Encryption layer

Phase 3: Room Management

• Room creation/joining
• Player management
• Host migration
• Room persistence

Phase 4: Game Support

• Warcraft III protocol support
• Red Alert 2 protocol support
• Game detection system
• Auto-configuration

Phase 5: Performance & Features

• Latency optimization
• Bandwidth management
• Chat system
• Statistics dashboard

🛠️ Technical Details

Network Protocol

• Transport: UDP for game packets, TCP for control
• Encryption: AES-256 for packet encryption
• Virtual IP Range: 10.x.x.x subnet per room

Packet Flow

1. Game sends LAN broadcast/unicast packet
2. Virtual adapter captures packet
3. Client encrypts and tunnels to server
4. Server relays to target players
5. Target client decrypts and injects to local network

🔧 Configuration

Client Settings

{
  "ServerUrl": "https://your-server.com",
  "DefaultPort": 5000,
  "EncryptionEnabled": true,
  "AutoConnect": false
}

Supported Games

Game	Protocol	Port	Status
Warcraft III	UDP	6112-6119	Planned
Red Alert 2	IPX/UDP	1234	Planned
Counter-Strike 1.6	UDP	27015	Planned

📦 Dependencies

• SharpPcap - Packet capture
• PacketDotNet - Packet parsing
• SignalR - Real-time communication

⚠️ Important Notes

Network Adapter Requirements

• Application requires administrator privileges
• May need to install TAP-Windows adapter
• Windows Firewall exceptions may be needed

Security Considerations

• All traffic is encrypted by default
• Room codes are randomly generated
• No data logging on server
