Features and Benefits
pfSense has many features that make it a powerful firewall and router solution. Some of the key features and benefits of pfSense include:
Firewall
pfSense provides stateful packet inspection, which means it can examine network traffic and block or allow it based on predefined or custom rules. pfSense can also filter traffic based on source, destination, protocol, port, or application. pfSense supports both IPv4 and IPv6 networks, as well as NAT (Network Address Translation) and port forwarding.
VPN
pfSense supports various VPN protocols, such as IPsec, OpenVPN, WireGuard, L2TP, PPTP, and SSL. VPNs allow secure remote access to the network from anywhere in the world. pfSense can also act as a VPN server or client, depending on the needs. pfSense supports hardware acceleration for VPN encryption, which improves performance and reduces CPU load.
Intrusion Detection and Prevention
pfSense can integrate with Snort or Suricata, two popular open-source tools for intrusion detection and prevention (IDS/IPS). IDS/IPS can monitor network traffic for malicious activity, such as hacking attempts, malware infections, or data breaches. IDS/IPS can also block or alert on suspicious traffic, depending on the configuration. pfSense can use various rule sets from reputable sources to detect known threats.
Content Filtering
pfSense can also filter web content based on categories, domains, keywords, or URLs. This can help prevent access to inappropriate or harmful websites, such as pornography, gambling, phishing, or malware. pfSense can use SquidGuard or pfBlockerNG for content filtering, which are both open-source packages that can be installed from the web interface.

Installation and Configuration
To install pfSense, you need to download the installation media from the official website: . You can choose between different versions depending on your architecture (AMD64 or Netgate ADI), installer type (USB memstick or DVD image), console type (serial or VGA), and mirror location.
After downloading the installation media, you need to write it to a USB flash drive or a DVD disc using a tool such as Win32 Disk Imager or Rufus. Then you need to boot from the installation media on your target system. The installer will launch automatically and guide you through the installation process.
The installation process involves selecting the keyboard layout, partitioning the hard drive, setting the hostname and domain name, configuring the network interfaces (WAN and LAN), setting the admin password, reloading the configuration, and rebooting the system. Web Interface
pfSense software includes a web interface for the configuration and management of all included components. There is no need for any UNIX knowledge, no need to use the command line for anything, and no need to ever manually edit any rule sets. Users familiar with commercial firewalls catch on to the web interface quickly, though there can be a learning curve for users not familiar with commercial-grade firewalls.
To access the web interface, you need to connect a client computer to the same network as the LAN interface of the firewall. By default, the LAN IP address of a new installation of pfSense software is 192.168.1.1 with a /24 mask (255.255.255.0), and there is also a DHCP server running. If a client computer is set to use DHCP, it should obtain an address in the LAN subnet automatically. On the client computer, open a web browser such as Firefox, Safari, or Chrome and navigate to . The GUI listens on HTTPS by default, but if the browser attempts to connect using HTTP, it will be redirected by the firewall to the HTTPS port instead.
Enter the default credentials in the login page: username admin password pfsense. You will then see the dashboard, which shows an overview of the system status and some widgets that display useful information or allow quick actions. You can customize the dashboard by adding, removing, or rearranging widgets according to your preferences.
Menu Structure
The web interface has a menu structure that organizes the various configuration options and functions into logical categories. The main menu is located at the top of the page and consists of eight items: Status, System, Interfaces, Firewall, Services, VPN, Diagnostics, and Help.
Status: This menu contains pages that show various information about the system and network status, such as interfaces, gateways, services, logs, graphs, traffic shaper queues, etc.
System: This menu contains pages that allow you to configure various system settings, such as general setup, user management, routing, updates, certificates, backup and restore, etc.
Interfaces: This menu contains pages that allow you to configure the network interfaces on the firewall, such as WAN, LAN, OPTx, VLANs, bridges, etc.
Firewall: This menu contains pages that allow you to configure the firewall rules and features, such as NAT, aliases, schedules, virtual IPs, traffic shaper, etc.
Services: This menu contains pages that allow you to configure various services that run on the firewall or provide functionality to the network, such as DHCP server and relay, DNS resolver and forwarder, NTP server and client, SNMP agent and trap receiver, etc.
VPN: This menu contains pages that allow you to configure various VPN protocols and settings, such as IPsec, OpenVPN, WireGuard, L2TP, PPTP, SSL VPN server and client settings.
Diagnostics: This menu contains pages that provide various tools and functions for troubleshooting and testing purposes, such as ping, traceroute, packet capture, test port connectivity,
Command Prompt
pfSense also provides a command prompt interface for advanced users who prefer to use the shell or need to perform tasks that are not available in the web interface. The command prompt can be accessed either locally by connecting a keyboard and monitor to the firewall, or remotely by using SSH or the web interface console.
The command prompt interface has a menu that offers some common functions, such as assigning interfaces, setting IP addresses, resetting the web interface password, rebooting or shutting down the system, etc. You can also exit the menu and access the shell, which allows you to run any FreeBSD commands or scripts. However, you should be careful when using the shell, as you might break the configuration or damage the system if you are not familiar with FreeBSD.
To enable SSH access, you need to go to System > Advanced > Admin Access in the web interface and check the box for Enable Secure Shell. You also need to create a user account with SSH privileges under System > User Manager. To access the web interface console, you need to go to Diagnostics > Command Prompt in the web interface and click on Launch Console Window. You will then see a pop-up window that asks for your username and password.
Security and Performance
pfSense is designed to be secure and fast by default, but there are some steps you can take to further improve its security and performance. Here are some tips and best practices:
Update Regularly
Keeping your pfSense system up to date is important for fixing bugs, patching vulnerabilities, and adding new features. You can check for updates manually by going to System > Update in the web interface, or you can enable automatic updates by going to System > Update Settings and choosing a branch and frequency. You can also subscribe to the pfSense newsletter or follow the pfSense blog to stay informed about new releases and security advisories.
Use Strong Passwords
Using strong passwords for your admin account and other user accounts is essential for preventing unauthorized access to your firewall. You should avoid using default or easy-to-guess passwords, such as pfsense, admin, password, etc. You should also change your passwords regularly and use different passwords for different accounts. You can use a password manager tool to generate and store strong passwords securely.
Enable HTTPS
Enabling HTTPS for your web interface is recommended for encrypting your traffic and preventing man-in-the-middle attacks. By default, pfSense uses a self-signed certificate for HTTPS, which might cause browser warnings or errors. You can either ignore these warnings or errors, or you can replace the self-signed certificate with a valid one from a trusted certificate authority (CA). You can either obtain a certificate from a public CA, such as Let's Encrypt, or create your own CA using pfSense. Use Firewall Rules
Using firewall rules is essential for controlling the traffic that enters and leaves your network. You can create firewall rules for each interface, such as WAN, LAN, or OPTx, and specify the action (pass, block, or reject), the direction (inbound or outbound), the protocol (TCP, UDP, ICMP, etc.), the source and destination addresses and ports, and other options. You can also use aliases, schedules, and virtual IPs to simplify and organize your firewall rules.
By default, pfSense blocks all incoming traffic on the WAN interface and allows all outgoing traffic on the LAN interface. You can modify these default rules or add new ones according to your needs. For example, you might want to allow incoming traffic for certain services, such as web server, VPN server, or remote desktop, or block outgoing traffic for certain applications, such as torrent, gaming, or social media.
Use Traffic Shaping
Using traffic shaping is useful for prioritizing and managing your bandwidth usage. You can use traffic shaping to allocate bandwidth to different types of traffic, such as VoIP, video streaming, web browsing, etc., and ensure that they get the quality of service they need. You can also use traffic shaping to limit bandwidth for certain users, devices, or applications that consume too much bandwidth or cause congestion.
pfSense supports various traffic shaping methods, such as HFSC (Hierarchical Fair Service Curve), PRIQ (Priority Queueing), CBQ (Class Based Queueing), and FAIRQ (Fair Queueing). You can use the Traffic Shaper Wizard in the web interface to create a basic traffic shaping configuration based on your network scenario and requirements. You can also fine-tune your traffic shaping configuration by editing the queues and rules manually.
