How to install pfSense 2.3.3 the easy way!

In this article you will learn how to install pfSense 2.3.3 step by step. There were minor changes in the installation process and this time we will also use the provided pfSense Installation Wizard and try out how well it performs.

For this tutorial, I will install pfSense on Virtual Box, with 3 Network Interfaces assigned to it. Let's get started with it.


Part 1 Install pfSense 2.3.3

First of all, you need to create a bootable USB Stick with the pfSense image.

Be aware to make the correct choice for your purpose, there is a special installer for NanoBSD or the installation over a Serial Console on an embedded device like an APU1D4 for example.

There are tutorials on how to create a bootable USB stick on there too. We will not cover that here as you should be familiar with how to do so when you want to use pfSense in the first place. I recommend using Rufus.

This is also a difference between this version of the installer and earlier versions, in earlier versions you were still required to specify a LAN and a WAN interface, this is now assigned automatically, but can be changed at any time.

Part 2 pfSense basic configuration via Web Interface

Now the basic installation is done, connect a device to the LAN interface and open a web browser.

2.1 pfSense basic configuration via Web Interface

- Open a Web Browser and enter the address:
- Click on advanced and Add a security exception.


You can create a self-signed certificate later to ensure a secure connection, I got you covered on how to do that.

2.2 pfSense basic configuration via Web Interface

- Log in to the Web Interface with the credentials:

Username: admin
Password:  pfsense


This is the first time we use the pfSense initial configuration wizard - it quickly runs you through all the important steps, I was satisfied with the result.

2.3 pfSense basic configuration via Web Interface

- Click Next


2.4 pfSense basic configuration via Web Interface

- Choose a Hostname and Domain if applicable, leave everything else as default and hit Next


2.5 pfSense basic configuration via Web Interface

- Select your timezone accordingly and let the time server on default or choose one of your flavor


Time to configure your WAN interface, this depends on what kind of connection you have, we in Germany mostly use PPPoE as Type and got provided with credentials from our ISP.

Research the proper MTU size for your connection and enter it here and if possible on your Modem.

2.6 pfSense basic configuration via Web Interface

- Change the type to PPPoE
- Adjust MTU Size


2.7 pfSense basic configuration via Web Interface

- Now enter the credentials provided by your ISP. If you don't know in which format to enter them, use Google, the information will be out there


2.8 pfSense basic configuration via Web Interface

- Leave the rest as it is and click Next


2.9 pfSense basic configuration via Web Interface

- Leave the LAN IP Address as default or change to your flavor
- Click Next


2.10 pfSense basic configuration via Web Interface

- Change your administrator password
- Click Next

Protip: Don't change it to pfsense :)


2.11 pfSense basic configuration via Web Interface

- Finally hit reload to reload your box with the just configured settings


If you did everything correctly, your pfSense should now be connected to the Internet, you can see this on the Dashboard and on the connection state of your WAN Interface.

We do one last thing, assuming you don't get a static IP from your ISP, your internet connection will reset every 24 hours. We want to move this reset time to a time when you are not at home or awake or let's say to a time when you can live with a short interruption of the connection.

2.12 pfSense basic configuration via Web Interface

- Go to Interfaces / WAN
- Scroll down to PPPoE configuration
- Change periodic reset to custom
- Enter a time of your flavor (for me it's 04AM)


There is also a video up on my YouTube Channel, although the video doesn't use the Wizard, so you can choose which way you prefer to do it 🙂
