This article explains a method of whitelisting one or more devices on your internal network so that pfBlockerNG doesn’t block those devices/servers due to any configured restrictions. For example, you might block a country using pfBlockerNG’s GeoIP filtering, but you may need one of your internal devices to be able

The firewall was receiving the following error message when reloading the filter rules (in “Status – Filter Reload“). There were error(s) loading

This article is a quick comparison of advert blocking for web browsing between pfBlockerNG DNS filtering, and the web browser plugin Ad Blocker. This is hardly scientific, but it does give an idea of how effective each are with basic settings. I’m sure with more effort, the impact could be

This article demonstrates the settings required on Windows and pfSense to get a Windows Built-In VPN to work between the two. It’s actually pretty easy. This article is more a confirmation of settings than a guide. Make sure you have the firewall rules configured on the pfSense WAN interface. We’re
Read moreI discovered this issue today while upgrading a Netgate 7100 from 22.05 to 23.01. The Reddit page “https://www.reddit.com/r/PFSENSE/comments/mdqyhg/unable_to_check_for_updates_getting_this_error/” discussed this topic too.

Recently I upgrade the disk of a Netgate 7100 1U firewall appliance. I’ve been looking forward to doing this but was not sure on the success of using a locally purchased (off the shelf) hard disk.

Recently a comment from “carefreepineapple” appears on this blog responding to this article “https://agix.com.au/restore-pfsense-from-backup-using-the-cli-command-line” where the problem differed slightly, and so did the solution. Here’s the solution to restoring a config file from a USB storage device. The idea being that one could copy a config file from a working
Read moreEDIT: I have seen this more recently where the total number of pfBlockerNG records exceeded the amount of rules accepted by pfSense (in Advanced-Firewall). I believe the issue relates to that limitation which can easily be overcome by increasing the acceptable maximum. Today I encountered a Netgate pfSense firewall that
