Secure Enterprise Network with FortiGate Firewall, IPSec VPN & High Availability

? Project Overview:

Designed and implemented a secure enterprise network infrastructure using FortiGate Next-Generation Firewalls, connecting a main site (Cairo) with a remote branch (Aswan) عبر IPSec Site-to-Site VPN.

? Key Features:

Secure Site-to-Site IPSec VPN between branches

High Availability (HA) using FortiGate firewalls (Active/Passive)

VLAN segmentation for departments (Management, IT, Employees, Servers)

Inter-VLAN routing داخل الشبكة

Network isolation and security policies

WAN connectivity simulation with multiple ISPs

Centralized network design with Core & Access layers

? What I Did:

Designed multi-site enterprise topology

Configured FortiGate Firewall (Interfaces, Policies, NAT)

Implemented IPSec VPN tunnel between sites

Set up High Availability (HA) for failover protection

Configured VLANs and trunking across switches

Applied security best practices for traffic control

? Result:

Achieved a highly secure, fault-tolerant, and scalable enterprise network ensuring secure communication between branches with zero downtime during failures.
