  • Next, remove the SD card from your PC or computer and insert it into the Raspberry Pi.
  • Using HDMI and USB Keyboard, edit the uENV.txt file and SERIAL-CONSOLE settings from ON to OFF. However, you should edit the config.txt file and enable uart=1 to the end if you use the serial console.
  • Connect everything to the Raspberry Pi after that, and turn it on.
  • Observe the standard IPFire installation and configuration procedures.


  • Finally, configure the installed IPFire as you need.

3. NethServer

Another excellent Pfsense alternative for Raspberry Pi is NethServer. NethServer is a server-focused Linux distribution that is based on the famous CentOS. The distribution makes it simple to use as a mail server and filter, web server, groupware, firewall, or VPN server. This app can also act as a firewall or a gateway on the network where it is installed. That makes it a good alternative for Pfsense among Raspberry Pi users.

The NethServer firewall application includes features like:

  • Realtime network traffic charts
  • Firewall rules management
  • An intelligent search feature. That allows you to search for a particular object on the main dashboard easily.
  • Traffic shaping (QoS)
  • Detailed data inspection before being sent over a network (Deep Packet Inspection)
  • Port forwarding.
  •  Routing rules to divert traffic on a specific WAN

To get started with NethServer, follow the steps below.

  • First, you need to download and install NethServer on your Raspberry Pi.
  • Navigate to this website and download the CentOS image for Raspberry Pi 4.
  • First, download the centos.
  • Use a tool like Balena Etcher or RPI Imager to flash the OS to the Raspberry SD Card.
  • After successfully writing the image on the SD Card, insert the SD card into the PI and power it up.

Up to this point, you have successfully set up CentOS on your Raspberry Pi. Next, you need to download and install NethServer. Follow the steps below.

  • Add the NethServer repository by executing the command below.
yum install http://packages.nethserver.org/nethserver/7.9.2009/arm-base/armhfp/Packages/nethserver-release-7-19.ns7.noarch.rpm
  • When done, install the base system by executing the command below. Please note that this step might take several minutes.

5. Configure Raspberry as Router – Firewall Using Iptables

The last item on this list will be using Iptables to configure your Raspberry Pi to act as a router. Iptables is a built-in firewall that comes pre-installed on most Linux distributions. This firewall filters network packets according to a set of pre-defined rules. That enables users to manage connections by accepting, refusing, or rewarding.

Before starting with Iptables, you must install the official Raspberry Pi OS. Once done, launch the Terminal and execute the command below to enable routing, which is disabled by default.

iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE

Next, we need to configure the Pi to accept traffic from the Ethernet port (eth0) and allow connections from the wireless interface (wlan0) to the eth0 interface. Use the commands below.

iptables -A FORWARD -i eth0 -o wlan0 -j ACCEPT
iptables -A FORWARD -i wlan0 -o eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT


Any device can become a more reliable home router with the help of the excellent network security solution pfSense. However, because pfSense is still not compatible with the Raspberry Pi, you are only left with the option of trying out other pfSense alternatives or modifying your Raspberry Pi device’s software and hardware to make it function as a router with firewall support.

Firewall software secures networks and computers from attacks by filtering out unwanted network traffic and malicious apps. The top 5 Pfsense alternatives for Raspberry Pi are discussed in this article. Depending on your needs, you can select any option from the list.
