Hardware Requirements: What You'll Need

Alright, so you're sold on the idea of pfSense Plus? Awesome! But before we get to the fun part of configuring your free firewall, let's talk about the hardware you'll need. Don't worry, you don't need a supercomputer. A relatively modest setup can handle the demands of a home network. Some of this might be old stuff, so it doesn't have to be expensive. It will work as a home router.

Here's what you'll typically need:

A Computer: This is the heart of your pfSense Plus setup. You'll need a computer with a processor, RAM, and storage. An old desktop or laptop can often do the trick. A low-power, x86-64 compatible CPU (like an Intel Atom or Celeron) is generally sufficient. More processing power helps for handling high internet speeds, and for running extra packages like IDS/IPS. For home network setup, it works fine.
Network Interfaces (NICs): You'll need at least two network interfaces (NICs). One will connect to your internet modem, and the other will connect to your home network. You may need more if you want to create separate networks (e.g., a guest network). Make sure the NICs are compatible with the version of FreeBSD that pfSense Plus is running on. Check the official pfSense documentation for a list of supported hardware. You might want to get additional network cards. This depends on your particular situation and your needs. Be ready to buy those.
RAM: 1 GB of RAM is the absolute minimum, but 2 GB or more is recommended, especially if you plan to use advanced features or have a lot of devices on your network. More RAM can help handle traffic. You must evaluate the RAM necessary.
Storage: A hard drive or SSD is needed to store the pfSense Plus operating system and configuration files. A small SSD (32 GB or more) is generally sufficient. If you want to log a lot of data, you may need more storage. Be sure you have a valid storage before starting with pfSense installation.
Monitor, Keyboard, and Mouse: You'll need these to initially install and configure pfSense Plus. Once it's set up, you can typically manage it remotely via a web interface, so these aren't required for everyday use.
Internet Connection: Obviously, you'll need a working internet connection to test your new firewall and to connect your home network. This is required for home internet security.

Important Considerations: Don't be tempted to skimp on hardware. A low-powered or under-spec'd machine can lead to performance bottlenecks and a frustrating experience. Consider the maximum speed of your internet connection and choose hardware that can handle it. When setting up your home network setup, take this into account. Try to get the best hardware within your budget. You can always check pfSense vs. alternatives to see the differences and their characteristics.

Usually, you can access the BIOS by pressing a key (like Delete, F2, or F12) during startup. You need to boot from the USB drive. It's a common step for installing pfSense Plus.
pfSense Plus Installation: The pfSense Plus installer will start. Follow the on-screen prompts. You'll be asked to choose a keyboard layout, partition your hard drive, and select the installation type. For most home users, the default settings are fine. This is the pfSense for beginners way.
Configure Network Interfaces: During installation, you'll be prompted to assign network interfaces. The installer will detect your NICs. You'll need to assign one interface to the WAN (wide area network - your internet connection) and one to the LAN (local area network - your home network). Typically, the WAN interface is the one connected to your modem, and the LAN interface is connected to your switch or directly to your devices. This will help you to do the pfSense configuration and set your home network setup.
Set the LAN IP Address: The installer will ask you to set the IP address for the LAN interface. The default is usually 192.168.1.1/24. You can change this, but make sure it's within a private IP address range (e.g., 192.168.0.0/24, 10.0.0.0/24). This is a crucial step for your home network setup. This will help with your pfSense configuration.
Complete the Installation: Once the network interfaces are configured, the installer will copy the files and complete the installation. When finished, you'll be prompted to reboot your computer. Remember, the pfSense Plus installation is a critical step.
Access the Web Interface: After rebooting, you'll be able to access the pfSense Plus web interface from a computer connected to the LAN interface. Open a web browser and go to the IP address you assigned to the LAN interface (e.g., 192.168.1.1). You'll be prompted for a username and password. The default credentials are admin for the username and pfsense for the password. Remember this when accessing your pfSense configuration.
Change Default Credentials: The first thing you should do after logging in is change the default username and password. This is a crucial security step. You will be able to do this through the web interface. That's a good network security measure.

Congratulations! You've successfully installed pfSense Plus. Now it's time to start configuring your firewall.

Basic pfSense Configuration: Setting Up Your Firewall

Alright, you've got pfSense Plus installed, and you're logged into the web interface. Now comes the fun part: configuring your firewall! Here's a basic guide to get you started.

WAN Configuration: Go to Interfaces -> WAN. Here, you can configure your WAN interface settings. The settings will depend on how your internet connection is configured. If you have a static IP address, you'll need to enter it here. If you're using DHCP (most common), the settings should be obtained automatically. If you're having trouble with your internet connection, try the default DHCP, or contact your ISP. This will help with the pfSense troubleshooting.
LAN Configuration: Go to Interfaces -> LAN. Make sure the LAN interface has a static IP address in a private IP range (e.g., 192.168.1.1/24). This is the address that your devices will use to connect to the network. You can change the LAN interface. It is part of the pfSense configuration.
Firewall Rules: Go to Firewall -> Rules. Here, you can create rules to control what traffic is allowed in and out of your network. The default rules usually block all inbound traffic and allow all outbound traffic. This is a good starting point. You will want to customize these rules based on your needs. Check your rules to improve your network security. You will have to do this based on your pfSense configuration.
Enable DHCP Server: Go to Services -> DHCP Server. Enable the DHCP server on your LAN interface. This will automatically assign IP addresses to devices on your network. Configure the IP address range. It's an important part of your home network setup.
DNS Configuration: Go to System -> General Setup. Configure your DNS servers. You can use your ISP's DNS servers or public DNS servers like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1). This helps with the pfSense configuration.
NAT Configuration: Go to Firewall -> NAT. Ensure that you have a NAT (Network Address Translation) rule set up on the WAN interface. This is typically configured by default, and allows your devices to access the internet. NAT will work as your home router.

This is just a basic configuration to get you started. pfSense Plus has many advanced features that you can explore. These steps will help you with your pfSense for beginners project. This will help with the pfSense security.
