What is pfBlockerNG in pfSense?

BBCan177’s pfBlockerNG is a pfSense® software package for IP/DNS-based filtering. It is based on Marcello Coutinho’s and Tom Schaefer’s earlier work.

The purpose of the project was to enhance the primary firewall functionality of pfSense by letting users to monitor and manage inbound and outbound access through the firewall using IP and DNS control lists.

pfBlockerNG allows pfSense® software to make allow or deny choices based on factors such as an IP address’s geolocation, a resource’s domain name, or the Alexa ratings of the websites.

Most of pfSense® software users believe that pfBlockerNG is an excellent package and that a pfSense® installation would be not complete without it.

pfBlocker: Features

There are features that we can get with the pfsense pfblockerng setup. GeoIP blocking is present in the pfBlocker. This gives us control over the geographic regions that join to the network.

This may be found in the pfBlockerNG menu under IP-GeoIP. Websites contain material and media on servers all around the world, so be cautious about banning too much.

Blocking any of these IP addresses without condition may result in trouble causing websites or downloads that we cannot access.
