# Configuring pfSense Firewall Rules ## When to Use - Deploying a perimeter or internal firewall to segment and protect network zones (DMZ, internal, guest, IoT) - Creating granular access control rules to restrict traffic between VLANs and network segments - Configuring NAT rules for port forwarding to internal services exposed to the internet - Setting up site-to-site or remote access VPN tunnels using IPsec or OpenVPN - Implementing traffic shaping and bandwidth management for quality-of-service requirements **Do not use** as a substitute for host-based firewalls on individual systems, for SSL/TLS deep packet inspection without dedicated hardware acceleration, or as the sole security control without complementary IDS/IPS. ## Prerequisites - pfSense 2.7+ installed on dedicated hardware or virtual machine with at least two network interfaces - Access to the pfSense WebConfigurator (default: https://192.168.1.1) - Network topology diagram showing all interfaces, VLANs, and desired traffic flow - DNS and DHCP configuration planned for each network zone - Understanding of TCP/IP, NAT, and stateful firewall concepts ## Workflow ### Step 1: Configure Network Interfaces and VLANs Access the pfSense WebConfigurator and define interfaces: ``` Navigate: Interfaces > Assignments WAN Interface (igb0): - Type: DHCP or Static IP from ISP - Block private networks: Enabled - Block bogon networks: Enabled LAN Interface (igb1): - IPv4: 10.10.1.1/24 - Description: CORPORA...
