IP Deny List is generating at this moment !

It could had been a setting I did miss on the IP Configuration page:
Firewall / npfBlockerNG / IP

At "IP Interface/Rules Configuration" browser I did highlight both (WAN & LAN) options (both since frankly I don't know which to choose) at:

• Inbound Firewall Rules
• Outbound Firewall Rules

Then I did follow your steps to "Force Reload"

I do apologize for error on my side, in setting up pfBlockerNG; I hope this will help someone else too.

Thank you BBcan177 & RonpfS for your help and time on this.

Thank you

Did you go to Firewall / pfBlockerNG / Update and did a Force Reload All ?

One thing that may fix some issues is to go to General, IP and DNSBL tab and click on Save settings. Then run a Force Reload All

Here are the re-install logs:

• I did try to uninstall (for a re-install) pfBlockerNG-devel, version 2.2.5_17 ; and the dialogue shows :Please wait while the update system initializes"; No more lines were generated (Same with 2.2.5_16 did happen); yet the package looks like got uninstalled when I check Packages page.

• Did reboot pfSense router; and re-install 2.2.5_17 package; no errors like 2.2.5_16 I saw before:

"PHP errors

• Restarted both services:
  pfb_dnsbl pfBlockerNG DNSBL service
  pfb_filter pfBlockerNG firewall filter service

• No IP List shows up.

I am not very fluent with pfSense setup; I could have missed a setting; the more details you do give me on how to troubleshoot, the better it is. I don't mind neither sharing the logs (be detailed on obtaining them) since I might miss on what could be a clue.

Below, is an image of the IPv4 IP feeds I did add:

When you say 'I assume that you enabled logging for these IP Aliases?' is there a check mark I need to make sure it is ticked?

Thank you for your help, and the program : )
