A simulated enterprise network built on Proxmox, integrating routing, security, identity, wireless, and monitoring into a single cohesive architecture.
This project demonstrates a real-world enterprise network design, combining:
- π£οΈ Advanced routing (Multi-area OSPF)
- π High availability (VRRP)
- π§© VLAN segmentation
- π₯ Firewall & gateway (OPNsense)
- π Identity & AAA (Cisco ISE)
- π‘ Wireless infrastructure (Cisco WLC + AP)
- πͺ Directory services (Active Directory, DNS, NTP)
- π Monitoring (Zabbix)
All core services are deployed inside Proxmox, simulating a private cloud environment.
| Service | VLAN | Subnet |
|---|---|---|
| π Cisco ISE | VLAN 10 | 10.100.10.0/24 |
| π‘ Cisco WLC | VLAN 20 | 10.100.20.0/24 |
| πͺ AD / DNS / NTP | VLAN 30 | 10.100.30.0/24 |
| π Zabbix | VLAN 40 | 10.100.40.0/24 |
OPNsense acts as the central security and routing point:
- π₯ Firewall (NAT & policy control)
- π Inter-VLAN routing
- π Internet gateway
