Network Segmentation, Central NAT, VIP, and Strict Firewall Policies
A secure 3-tier enterprise network simulation using FortiGate and GNS3:
- ✅ Zone Segmentation (LAN, WAN, DMZ) for minimized attack surface
- ✅ Central SNAT for optimized NAT management and logging
- ✅ Virtual IP (Port Forwarding) to securely expose DMZ Web Server
- ✅ Security Enforcement (Implicit Deny) to prevent DMZ-to-LAN lateral movement
OSPF Multi-Area, EIGRP DUAL, Route Redistribution & Filtering
A complete CCNP-level routing lab covering:
- ✅ OSPF Multi-Area with Route Summarization
- ✅ EIGRP with DUAL and ECMP
