configuring-pfsense-firewall-rules
Configures pfSense firewall rules, NAT policies, IPsec/OpenVPN tunnels, and traffic shaping to enforce network segmentation and control traffic between zones such as DMZ, internal, guest, and IoT. Use when deploying a pfSense perimeter or internal firewall, setting up port-forwarding NAT, configuring site-to-site or remote-access VPNs, or applying QoS/bandwidth policies.

# 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
