@Laxarus

Thank you Laxarus,

It seems to have worked.

@Laxarus This worked for me as well. Though I had to search the web how to edit the file (the easiest way).

Therefore:

Addition for anyone struggling to find where to edit files on your pfsense system.

Go to Diagnostics --> Edit File --> insert the location of the file:

/usr/local/pkg/pfblockerng/pfblockerng.sh

Go to line number 1232 by filling it in the Go to line field.

That line should read:

s1="$(grep -cv ^${ip_placeholder2}$ ${masterfile})"

replace only (leave the rest intact):

masterfile

to

mastercat

Then follow the above instructions from @Laxarus https://forum.netgate.com/post/1219635

Ran into this issue today as well running on 25.07.1 with pfblockerNG-devel 3.2.7. Followed the steps outlined in this thread to edit the pfblockerng.sh file, then deleted/force reloaded all the lists, and all was well again. Thank you everyone in this thread for your your help and great instructions.

From:

To:
s1="$(grep -cv ^${ip_placeholder2}$ ${mastercat})"

Is it possible to update the pfSense package with a bug fix version?

FYI, this bug is still present on pfSense v2.8.1-RC and pfBlockerNG-devel v3.2.8

@borgotech Hello, the bug, has been fixed with the latest update of pfBlocker. Please, check, if you have the latest version. In Menu System -> Package Manager -> see, if its the latest version (Appears then highlighted in color Orange in Packagemanager) if an Update is avaible.

If all this doesnt help, you can still patch it manually, please read above post by mull0r above here, who replies to Laxarus, he describes how to patch, in short, you have to login to your pfsense via SSH, and then:

sudo nano /usr/local/pkg/pfblockerng/pfblockerng.sh

then look for the line that contains. use ctrl w for to use nano editor search, and paste in:

s1="$(grep -cv ^${ip_placeholder2}$ ${masterfile})"

and change that line to:

s1="$(grep -cv ^${ip_placeholder2}$ ${mastercat})"

then, save it, with ctrl o, and leave nano, then just restart pfblocker, and the problem should be gone (worked for me, before last update been release a week ago approx.)

Thats it. Now, its should be fixed in the new Update of pfblocker, the Trick / Patch, is only necessary if you have a outdatet pfBlocker installed on your System.

Good Luck!

@TommyMoo
Thank you very much for the answer, as I mentioned above I am on the latest version of PfblockerNG devel pfBlockerNG-devel 3.2.10 and the latest stable version of PfSense+ Version 25.07.1-RELEASE (amd64). The patch in your post and the previous ones do not work because the changes have already been made to the latest version.

Anyway, thanks again..
