PfBlocker

@jp141:

1.) Have its own log tab so you can quickly and easily see what has been blocked

pfblocker just create firewall rules with log options selected, so there is no way to distinct from other firewall log rules

You could create the rules with 'label pfBlocker' and get stats based on that.
pf(4) allows that and this will give you stats.

Is it possible to include label on firewall rules gui?

Yes, the description that you put on the rules transforms into the label option behind.
Beaware that is limited to 64 chars in pf(4)

Maybe it's the way I get rules counters on widget. I'll see how can I use it in logs.

Thanks ermal for this tip.

I've read some of the posts regarding the Level 1 block list.

I have to say, the L1 the biggest list I use and I use a lot of lists.

My experience is that pfBlocker loads faster and more reliably when it has more efficient lists to work with.
For Level 1 - I converted it into CIDR and then broke that into 3 separate lists. It really helped.

You can try it yourself and see if performance improves.
Here's a converted L1 from Bluetack/IBlocklist - that I did last March.
The urls below will plug directly into pfBlocker-> Lists, or into Aliases.

FYI: To do this, I use Bluetack's Blocklist converter.
http://www.bluetack.co.uk/converter/

It's old and always takes me a few tries to get it right.
It's the only online tool I've found that will do the conversion properly.

My in-laws are traveling cross country and I was forced to start using Skype.
The thing is, I despise ads.

So, I've puzzled out the list of servers that deliver ads to Skype.

It was tricky, because Microsoft has ad servers and Microsoft services (like Hotmail) in the same IP blocks - and the IPs can switch every 5-10 minutes.
I had to write a couple of bash scripts to compile and separate ad-serving IPs from the service IPs.

Important -> You'll need to block outbound LAN connections for HTTP and HTTPS.

You can download the list from here. You could also use the url directly in pfBlocker or in Aliases.

It'll be updated when/if new ad servers make themselves known.

good job :)

Do you know about android ads on free apps? it's really annoying!

Hi there.. good day.. I am new to this pfBlocker, how to apply the pfBlocker rules to grouped interface, such as if i have grouped multiple WAN interface on pfSense setting..

thank you very much…

Change list action to alias only and create rules the way you want.

pfblocker began to fill my logs with "php: : There were error(s) loading the rules: /tmp/rules.debug:17: cannot define table pfBlockerNorthAmerica: Cannot allocate memory pfctl: Syntax error in config file: pf rules not loaded - The line in question reads [17]: table <pfblockernorthamerica>persist file "/var/db/aliastables/pfBlockerNorthAmerica.txt".

Seemed to work stable till today. The only thing i did was entering an own blocklist and put USA to my list.

Disabling the North America rules resolved the filling of systemlog, but the blocking remains down. :(

At the dashboard the widget shows all blockings as "down", say a red arrow.

New errors came up too:
php: : The command '/usr/bin/grep -v '^#' '/var/db/aliastables/pfBlockerTopSpammers.txt.tmp' > '/var/db/aliastables/pfBlockerTopSpammers.txt'' returned exit code '1', the output was ''

Did you increased max_table_entries on system -> advanced?

you may need to disable lists before increase max_table value.

_igor_

yes. I increased the max tables before. I had pfblocker disabled before i increased the max tables.

marcelloc

try to increase to a higher value.

_igor_

increased to 400000, but still all Blockings down. :(

@_igor_:

increased to 400000, but still all Blockings down. :(

I had to set mine to 999999999 before it all acted nice. Havent noticed any other issues with the increase.:-)

_igor_

Increased size to 999999999, but its still not working, say the status is still down. Reinstall didnt help too. :(

Did you disabled the server before increasing the value? You need a config apply without errors before trying a new value or a new list.

Also, check custom lists if any and diagnostic tables menu.

No errors, but Status is down. It shows cdir-entries, but no packets.

What action did you selected on pfblocker list? Did you enabled the service after installing?

_igor_

top spammers selected, activated.
