Project Title: Secure Network Deployment with FortiGate, MikroTik, and FortiAP InfrastructureClient: Internal/Construction Site Network Setup

Role: Network & Security Engineer

Project Overview:Designed and implemented a secure, high-availability network infrastructure using Fortinet security appliances and MikroTik routing solutions to connect corporate and construction site networks. The deployment focused on secure remote access, load balancing, user segmentation, and centralized wireless management.

Key Responsibilities:

• Firewall Deployment: Configured FortiGate 61F and 41F with MAC-based security policies for endpoint control.
• SSL VPN Setup: Enabled SSL VPN on FortiGate 61F for secure remote access for authorized users.
• IPsec VPN Configuration:Established IPsec tunnel between FortiGate 61F and MikroTik router to securely connect the construction site.
  Set up site-to-site IPsec VPN between FortiGate 61F and 41F for inter-office communication.
  
• Wireless Infrastructure:Deployed and integrated FortiAP FA-221E with centralized control through FortiGate.
  Configured SSIDs with captive portal authentication and manually created user credentials for Wi-Fi access.
  
• WAN Optimization: Implemented SD-WAN for automatic link load balancing and failover based on real-time path quality (latency, jitter, and loss).
• Security Policies:Developed department-wise web filtering and access policies.
  Applied MAC-based policies for management users with full access.
  Centralized content filtering policies common to all users.
  

Technologies Used: FortiGate 61F, 41F, FA-221E, MikroTik RouterOS, SSL VPN, IPsec VPN, SD-WAN, Captive Portal, Web Filtering, MAC Policy, VLANs, Static/Dynamic Routing
