What You'll Need

Alright, before we get our hands dirty, let's gather our tools and gear. Here's what you will need:

  • A PC for pfSense: You'll need a computer to install pfSense on. Any old PC will usually work, just make sure it has two or more network interfaces (NICs). The more interfaces, the better, so you can separate your WAN, LAN, and DMZ traffic. If you want to go super efficient, consider a dedicated firewall appliance.
  • Mikrotik Router: Any Mikrotik router should do. The popular models of Mikrotik are great. It depends on your internet speed and network needs. The Mikrotik RouterBoard is an excellent choice for most home and small business setups.
  • Network Cables: You'll need Ethernet cables to connect everything. Get a good mix of short and long cables, depending on your setup.
  • USB Drive: You'll need a USB drive to install pfSense. It is often used to boot from.
  • Monitor, Keyboard, and Mouse: You will need these to set up the pfSense box. You can unplug them after you are done with the initial setup.
  • Internet Connection: Obviously, you will need a working internet connection. Make sure you know your internet connection type (static IP, DHCP, PPPoE) from your internet service provider (ISP).
  • pfSense ISO Image: Download the latest version of the pfSense software from the official website. Make sure you get the right ISO for your PC's architecture (usually amd64).
  • Rufus or Etcher: You will need a utility like Rufus (Windows) or Etcher (Windows, macOS, Linux) to create a bootable USB drive with the pfSense ISO.

Setting Up pfSense

Okay, guys, let's get into the main stuff! This part is about installing pfSense. Follow these steps to install pfSense.

  1. Create a Bootable USB:
    • Use Rufus or Etcher to flash the pfSense ISO to your USB drive. Make sure you select the correct drive and that you are okay with all of the data being erased.
  2. Boot from USB:
    • Plug the USB drive into your pfSense PC and boot the computer. You might need to change the boot order in the BIOS/UEFI settings to boot from the USB drive.
  3. Install pfSense:
    • At the pfSense boot screen, select the default option to start the installation. If something happens to be wrong, this is the time to start over. If everything goes right, it should ask you to accept the license agreement. Then, you will be prompted to select a keyboard layout. Choose the correct keyboard layout, then choose to install pfSense.
    • Select the installation method: Guided or Manual. The guided method is simpler. It will prompt you to select the hard drive to install pfSense on. Select the drive, and then choose to use the entire disk. If you chose the guided method, it should start installing. Once the install is done, you will be prompted to reboot.
  4. Initial Configuration:
    • After the reboot, the pfSense console will be displayed. This is where the magic happens. Now, you should connect your network cables to your network interfaces, with one for your WAN and one for the LAN.
    • If you have a static IP address from your ISP, you will configure the WAN interface here. If you have DHCP, it will get the IP address from the ISP automatically.
    • Configure your LAN interface. Set up a static IP address for the LAN interface, e.g., 192.168.1.1/24. This will be the IP address you will use to access the pfSense web interface later.

After you've done all of this, you should be able to get access to pfSense via the web interface. Point your web browser to the IP address you configured for the LAN interface (e.g., https://192.168.1.1).

Configuring Mikrotik Router

Alright, time to get the Mikrotik router involved. The aim here is to set up your Mikrotik router to work seamlessly with pfSense. The Mikrotik router should handle the connections from devices. The pfSense firewall will protect the network from outside sources. Let's make sure that traffic is being routed correctly.

  1. Connect to Mikrotik:
    • Connect to your Mikrotik router using Winbox (a Windows utility), or use the web interface.
    • Make sure your Mikrotik router can obtain an IP address from pfSense. Connect your Mikrotik to the pfSense LAN interface using an Ethernet cable.
  2. Configure WAN Interface (Optional):
    • If your ISP requires a specific connection type (like PPPoE), configure the WAN interface on your Mikrotik router to handle this. You can do this in the IP > DHCP Client or PPP section of Winbox. This is the Mikrotik router, so only do this if you need to.
  3. Configure LAN Interface:
    • Set up the LAN interface (usually ether2 or similar) with a static IP address within the same subnet as your pfSense LAN interface (e.g., 192.168.1.2/24). Be sure that it is a unique IP address.
  4. Set Up DHCP Server:
    • Configure a DHCP server on your Mikrotik router to assign IP addresses to devices on your LAN. Go to IP > DHCP Server > DHCP Setup and follow the wizard.
    • Specify the IP range, gateway (the IP address of your pfSense LAN interface), and DNS servers.
  5. Configure DNS Settings:
    • Under IP > DNS, configure the DNS settings. You can use your ISP's DNS servers or public DNS servers like Google DNS (8.8.8.8 and 8.8.4.4).
  6. Set Default Gateway:
    • In IP > Routes, ensure that the default route points to the IP address of your pfSense LAN interface.

Once this is done, the Mikrotik router should be able to obtain an IP address from pfSense. All of the devices connected to the Mikrotik should now get their IP addresses from pfSense.

Finalizing the Setup

We are in the home stretch, guys! Let's get everything working smoothly. We have a solid foundation, and now it is time to make sure everything is working as it should.

  1. Verify Internet Access:
    • Connect a device to the Mikrotik router and check if it can access the internet. Open a web browser and try browsing a website.
  2. Test Firewall Rules:
    • Go back to the pfSense web interface and review the firewall rules. Ensure that the default rules allow traffic on the LAN and block unwanted traffic from the WAN.
  3. Configure Port Forwarding (If Needed):
    • If you need to host services (like a web server) on your local network, you'll need to configure port forwarding in pfSense. Go to Firewall > NAT > Port Forward and create rules to forward traffic from the WAN interface to the internal IP address of the service.
  4. Security Measures:
    • Enable pfSense features, such as intrusion detection, intrusion prevention, and VPN services. This is where you can beef up your network's security.
  5. Monitor Your Network:
    • Use the pfSense and Mikrotik tools to monitor your network traffic. This can help you identify any issues and optimize performance.
