I recently purchased Netgate’s entry level pfSense solution, the Netgate SG-1100. The Netgate SG-1100 is a small, but powerful network/security hardware device with the open source pfSense software. Netgate is a company with a great mission statement to make high quality security products available to consumers. I wanted to support Netgate, and the hardware best fit my needs for moving forward with my home lab.

What is pfSense?

“pfSense® software is a free, open source customized distribution of FreeBSD specifically tailored for use as a firewall and router that is entirely managed via web interface. In addition to being a powerful, flexible firewalling and routing platform, it includes a long list of related features and a package system allowing further expandability without adding bloat and potential security vulnerabilities to the base distribution. “

Home Network

Below is a diagram showing my home network after installing the Netgate SG-1100.

The Netgate SG-1100 shipped with the latest version currently available.

IDS Snort Package

Next, I installed the snort package from the pfSense package manager. The snort package was enabled on the LAN interface and set to Max-Detect.

Speed Test

Now lets compare the before and after enabling the IDS/IPS features in pfSense. For testing speeds, I will be using the open source tool speedtest-cli

Before pfSense installation / Control:


  • Ping 40ms-60ms
  • Download 9.5Mbps-10Mbps
  • Upload 2.40Mbps-2.80Mbps

After pfSense installation (Max Detection):


  • Ping 40ms-60ms
  • Download 8Mbps-10Mbps
  • Upload 2.30Mbps-2.80Mbps

As you can see, the speed was only slightly, if at all, affected by snort.

pfSense Resource Usage

Default Configuration Resource Usage

pfSense Enabled (Max Detection)

Resources on the SG-1100 have not been affected! I am still concerned about the 1GB of RAM, but of course I do not have a huge amount of traffic on my home network.


Overall, the Netgate SG-1100 has met my expectations as a flexible firewall, IDS/IPS and VPN for home use. I did not see any performance issues with pfSense, and my home network speed was not affected by enabling the IDS/IPS features. I have also yet to experience some of the cons mentioned in other reviews such as slow web application speeds. I highly recommend this device for any technical home user or small business.

Look for more blogs in the future about getting all the pfSense logs into Splunk for some useful dashboards. Until next time, stay safe in the Trenches of IT!
