This project simulates a small ISP / enterprise network using VirtualBox.
Goals:
- VLAN-based network segmentation
- Centralized routing and firewalling
- External DHCP/DNS service
- Monitoring and logging
- Infrastructure as Code mindset
Limitations:
- Single physical NIC
- WAN simulated via VirtualBox NAT
VyOS version:
- Image: VyOS rolling release
- Reason: LTS builds are subscription-only
- Version is pinned and not updated to ensure reproducibility
