Tastler Networks & Security

Projects

My Technical Projects:

2026

ECN2026 – European Connected Network
  • Target: Simulation of a European multi-site network (Sweden ↔ Switzerland ↔ Germany) using enterprise concepts on limited hardware
  • Implementation: Three-tier campus architecture with routing, site-to-site VPN (WireGuard), firewalling & AS simulation – structured in three phases (Core Connectivity → Multi-Site → Security & Operations)
  • Result: Growing network lab with cross-site routing, documented architecture and configuration examples on GitHub

2025

Network Projects:

  • Webserver with Nginx
    • Target: Deployment of a secure and maintainable web server for personal services
    • Implementation: Nginx as a reverse proxy in a Docker environment on Linux with TLS encryption (Let's Encrypt)
    • Result: Stable, containerised web server with HTTPS, automatic certificate renewal & clear separation of services
  • WireGuard VPN Server
    • Target: Secure remote access to internal systems and services
    • Implementation: Self-hosted WireGuard VPN server on Ubuntu with nftables firewall
    • Result: Stable client-to-site VPN operation with automatic startup, key management & monitoring
    • Note: Preparation for future site-to-site connectivity of multiple networks
 

Programming Projects:

  • Portscanner in Java
    • Target: Analysis of open TCP/UDP ports for network diagnostics and security auditing
    • Implementation: Java-based port scanner with multithreading for parallel scans and timeout handling
    • Result: Fast, reliable scanning tool for identifying reachable services in the network
  • Portscanner in Python
    • Target: Automated network and port analysis for basic security checks
    • Implementation: Python-based CLI port scanner with scripting approach and modular structure
    • Result: Easily extensible scanning tool for quick network overview and automation
