PfBlockerNG v2.0 w/DNSBL

RonpfS

I did notice that when I did a new install with the latest pfsense software and loaded pfblockerng that the floating rules for the VIP 10.10.10.1 were not created even though I had all the interfaces checked along with the floating rules box. I could not get any blocking until I manually created the floating rule for the vip.

I did try to check and recheck the settings and also restarted pfblockerng and restart the system multiple times until I discovered that the floating rule was missing.

Everything works as it should now, even blocking the youtube ads and porn.

I have been using pfsense and pfblockerng and before that the pfblocker. I love the package!!!

A fix for this issue is being tested.

@duanes:

Also, changed the config.inc file so that AMD64 = 4096M

PHP ERROR: Type: 1, File: /usr/local/pkg/pfblockerng/pfblockerng.inc, Line: 3867, Message: Allowed memory size of 134217728 bytes exhausted (tried to allocate 72 bytes)pkg: POST-INSTALL script failed

Did you reboot after making the modifications ? Maybe the ini settings are not loaded without the reboot.

134217728 show that the max memory configured somewhere is still 128M.
Maybe you are pushing the limit too far and it resets to 128M
Most users are running fine with 512M, 640M or maybe 768M, using 4096M per PHP process on a 4GB system doesn't make sense.

Double check the modifications you made and try again.

Hi all,

I'm also having this issue. However, I don't know where you guys are finding the file to edit. I see that the location of the file is /etc/inc/config.inc but how do I get to it to edit? I'm only familiar with pfsense through the web interface.

Thanks in advance for your help!

Maybe you should read this https://forum.pfsense.org/index.php?topic=102470.msg647719#msg647719 again

I read it, but only for the amd64, not the i386. But started over and noticed it. Thanks again for your help and patience!

I made modifications to the post in the last days to better explain the fixes.

Hey Ron,

Going to start following this thread. Hopefully BBCan will chime in soon; do we know if there is an optimal fix in-work to deal with the MaxMind changes? The workaround procedure worked for, but find it odd to see these tables growing at an alarming rate.

M

The tables are built from MaxMind GeoIPLite2 database, pfblockerNG just take the db and create the files for it's usage. MaxMind support has been contacted about the size being 3x larger than before.

In the Status/System Logs / Settings there is the option "Show log entries in reverse order" is this possible for the log browser in pfBlockerNG?

Cheers Qinn

System logs are one liner, pfblockerng.log is formated to be read top to bottom.

Here are more DNSBL Feeds that can be used in pfBlockerNG.
(Copy and paste URLS as plain text)

Create a new alias for these.
These are not necessarily ADvert domains. So I named mine "Malicious"

These two feeds post full URLs, so there can be some more false positives.
Create a new Alias, and use Alexa as a recommendation.

This is a feed that I manage (as time permits)
MS_2
https://gist.githubusercontent.com/BBcan177/4a8bf37c131be4803cb2/raw

Use this in its own Alias:

http://osint.bambenekconsulting.com/feeds/dga-feed.gz

BBC_C2
http://osint.bambenekconsulting.com/feeds/c2-dommasterlist.txt

Use this feed in its own alias as it is updated more frequently.
So you can update it more often than once per day.

If users find other feeds, please post back so that others may benefit also.
Its also important to donate to the feeds provider (IP and/or Domain) as they all need support.

I got a

…..are the use of the sources mentioned above still to be advised? My Count went from 78k to a 476k and looking at the packets those extra 400k doesn't seem to be highly effective.

Thanks for any advise,

The http://adblock.gjtech.net/?format=unix-hosts doesn't seem to be available anymore.
Just turn the list state to OFF.

Thanks RonpfS for the reply.

I set this up last night and so far good other than certification error pop ups i keep getting on certain sites. Anyone know if there is a fix for this?

Also, do you guys use IPv4 lists and DNSBL or just one?

RonpfS

Try Chrome or Firefox.

@RonpfS:

Try Chrome or Firefox.

Not a fan or either. Any other option?

Nope, take a look at Reply #161 https://forum.pfsense.org/index.php?topic=102470.msg575727#msg575727

The way I resolved it is to permanently add cert… click show cert and choose trust check box this will add trust but when it resolves it is handeled dnsbl and returns 1x1pixel.

Here is a link to PR # 175 for pfBlockerNG v2.1.1_3

https://forum.pfsense.org/index.php?topic=115357.msg649167#msg649167

2.1.1_4 is out , hopefully the answer to all

Good morning. I'm having the cannot allocate memory issue after upgrading from 2.1.1_2 to 2.1.1_3, then to 2.1.1_4. Uninstalling and reinstalling with and without keep settings checked off and i am still getting the cannot allocate memory error in pfsense. I've also been doing a force update after each try just in case.

Looking at the pfblockerng.log i cannot see any errors or failures. see below for exact error from pfsense.

There were error(s) loading the rules: /tmp/rules.debug:46: cannot define table pfB_SAmerica_v6: Cannot allocate memory - The line in question reads [46]: table <pfB_SAmerica_v6> persist file "/var/db/aliastables/pfB_SAmerica_v6.txt" @ 2016-08-26 09:28:18

if it helps i have 16GB in the FW.

Thanks.

You should have leave you original post in the pfBlockerNG v2.1 w/TLD thread.

It is mentionned many many times that if you are using GeoIP tables, you need to raise Firewall Maximum Table Entries in System / Advanced / Firewall & NAT

The file on my pfsense is called South_America_v6.txt, maybe you have leftover from the previous installation. Open the Africa GeoIP tab, verify your selections and hit save, this will update the table. Then run Force Reload IP.
I just enabled the South America GeoIP table on my system and it has the same name as yours pfB_SAmerica_v6, so it is probably just a table size issue.

Thank you I raised it to 4.5M to be safe.

I pulled it out of there because it looked like that forum was for the dnsbl tld. Many people get annoyed when something is posted in the wrong place.

I also saw that but thought it may no longer applicable once the php updates for pfblockerng were released. I thought that was a short term fix only until the next release.

Once again thank you.
