This project showcases the design and deployment of a segmented network architecture using pfSense as the central firewall and routing solution. The setup includes two isolated LANs—LAN-11 and LAN-12 each configured with distinct IP ranges and gateway addresses, and a WAN interface for Internet access.

Using three virtual NICs, I emulated a real-world network environment:

LAN-11 (192.168.11.0/24) via Host-only Adapter 1

LAN-12 (192.168.12.0/24) via Host-only Adapter 2

WAN-1 via NAT Adapter 3 for external connectivity

The pfSense firewall was configured to manage traffic between these segments, enforce access control policies, and provide NAT services. This implementation demonstrates my ability to:

Architect secure multi-LAN environments

Configure firewall rules and routing policies

Simulate enterprise-grade network setups using virtualization

The project culminated in a functional, secure network topology ideal for testing, training, and small-scale enterprise use.
