🛡 End-to-End Web Security Architecture: FortiWeb WAF + FortiGate in Reverse Proxy Mode
Recently completed a comprehensive lab implementation and full documentation of a production-grade web security architecture using FortiWeb as a Web Application Firewall behind FortiGate, deployed on PNETLAB with KVM-based VMs.
🔹 Traffic Flow Architecture:
Client → FortiGate (WAN/VIP) → FortiWeb (WAF Inspection) → Apache2 Real Server → Response back to Client
🔹 Key Implementation Highlights:
✅ Linux Web Server hardening with Apache2 and static IP configuration via Netplan
✅ FortiWeb interface setup across three segments (Real Server / Client-LAN / Management)
✅ Complete WAF policy chain: Virtual IP → Server Pool → Virtual Server → Server Policy
✅ FortiGate perimeter configuration with DNAT Virtual IP (100.100.100.50 → 192.168.100.50)
✅ Firewall policy with full session logging for HTTP/HTTPS/PING traffic
✅ CLI-based traffic logging activation on FortiWeb (a step many engineers miss!)
✅ End-to-end verification through Forward Traffic logs on both devices
🔹 Why Reverse Proxy Mode?
It provides deep HTTP/HTTPS inspection, granular WAF policy enforcement, and clean separation between perimeter firewalling (FortiGate) and application-layer protection (FortiWeb) — a layered defense approach aligned with Zero Trust principles.
🔹 Key Lesson Learned:
The order of WAF policy configuration matters → Virtual IP must exist before the Server Pool, which must exist before the Virtual Server, which must exist before the Server Policy. Skipping the sequence breaks the binding chain.
💼 Currently exploring new opportunities in Network & Cybersecurity Engineering — open to on-site, hybrid, or remote roles. I deliver hands-on services in network design, firewall deployment (Fortinet, Cisco), WAF implementation, ICS/OT security (IEC 62443, NIST), and infrastructure hardening.
