BBcan177, first of all great work on this package, it's a must have to all pfsense boxes.

I found a bug! If we can call it a bug, it can be only miss configuration.

Lets assume this scenario. 2 Lists, 2 Interfaces.

I have list 1 (IP's)
1.2.3.4
5.6.7.8

I have list 2(IP's)
1.2.3.4
9.10.11.12

Both have IP 1.2.3.4

I make use of De-Duplication.

I set list 1 as Deny on Interface LAN1
I set list 2 as Deny on Interface LAN2

The logs are all messed up, because He can't find out that from what interface the block 1.2.3.4 is.

Best Regards

Hi soloam,

Its not a bug. When you use de-duplication, only one of the Lists will have IP 1.2.3.4
If you want a second list to skip de-duplication, you will need to use "Alias Native" and manually create the firewall rule…

That was my solution. :)

Thank you BBcan177.

Hello all, just to make one question.

I what to see the complete list of IP's on a alias. So i'm looking at Diagnostics > Tables and selecting the alias table. When I do this I get a blank page and in pfsense the alert:


Crash report details:

PHP Errors:
[15-Oct-2015 15:55:19] PHP Fatal error:  Allowed memory size of 268435456 bytes exhausted (tried to allocate 115824003 bytes) in /usr/local/www/csrf/csrf-magic.php on line 157

Can any one tell me if it's possible to resolve this?

Thank you.
Best Regards

From pfBlockerNG General tab scroll down to Rule order and change it to
|pfSense Pass/Match | pfB_pass/Match | pfB_Block/Reject|

Click save and go check your rule order it should be the way you want it

@BBcan177:

Well its kind of what the name of the package implies :)
So to answer your question, yes the package can create firewall rules to "Block/Reject/Permit/Match"…

Need more info on how you have configured it to help you further.

I am currently studying the thing. Once I think that I know what is going I'll be back…

Some IPs are actually blocked, but I don't know exactly why. I am using "| pfB_Block/Reject | All other Rules | (original format)"

@heliop100:

Currently, no… That would require creating a cookie so that when the Alerts Tab reloads each minute, it could load any filter settings stores in the cookie... Maybe in a future release...

Loading really large files into the browser can cause issues… Try to use the pfBlocker Log tab (Which also might have issues with these large files) or view the files from the shell. Files are located in the following folders:

/var/db/pfblockerng/deny or /permit or /match or /native

You can view these files with your choice of file editor like vi or ee…

Sometimes after cron has run and i read the log file it has a very small number at the end which does not correspond to the total addition of the numbers on the block files.

This is fixed with a force reload and the number matches the number above in the log file. (its usually about 1/8th the number)

Another thing I've noticed is the number on the widget shown after deny does not correspond to either of these numbers and I'm not using de-duplication so why is that? And is there anything i can do to investigate?

Thanks

Rob

UPDATE: BBcan177 confirmed this issue is just a timing issue and how to check it.

Hello eveybody,

So im trying to block TOR, I wrote this script to collect TOR exit nodes, and write it to a txt in a web server. So pfBlocker goes and downloads this file and adds the IPs, as shown below;

Then it adds the rules to the firewall, but is not blocking any of the IPs. Can you guys help me … what Im doing wrong??

Thanks

Can you show the rules that are added?

@hulleyrob:

Thank you for your reply, here you go

The first screenshot is WAN, to block from the outside and just added outbound too.
Next is LAN with it its default rules plus the auto block.
The last one is for my office branch, in which the rule for 10.4.2.3 is to get acces to the internet via squid/dansguardian at port 3128 on that pfsense.

Where are you seeing these, can you post the log showing the TOR traffic entering your network?

Also should the WAN only be blocking TCP TOR traffic? (because it is, not * like the others)

Is the Reputation Settings supposed to give the option to choose all 3 :
Individual List Reputation, Collective List Reputation (pMAX), Collective List Reputation (dMAX)

Reading the descriptions it seems as though the dMAX makes the most sense but I can't tell what the other 2 would mean– so then I don't know if I quite understand what's going on here.

Seems like that whole feature needs some fresh eyes to write the descriptions because it doesn't answer the what's and why's.

Also, on the same page, is the entire Emerging Threats IQRISK IPv4 Reputation section a subscriber feature or just portions of it? For clarity, if the section could be hidden unless a checkbox is checked or something it would help in knowing if it's relevant to those who don't pay for it. Just a thought.

Thanks!

[ [color=red]XML RPC Sync ] Improvements to http/https and Username. The 'General Tab settings' can also be excluded from the sync to allow for Site specific customizations.

Is the XML RPC Sync meant to support sync to an IPv6 address? When I try it with just an IP v6 address the sync times out because it is trying to use the address in a non-literal format. When I enter the address in the literal form with [] around it, I get the following error (which is the same when trying to use a host name).

php-fpm[26593]: /pkg_edit.php: [pfBlockerNG] XMLRPC sync terminated due to mis-configured Replication Target IP Address or Port settings.

I am already synchronising some of the pfSense config over v6 successfully.

@heliosfa:

php-fpm[26593]: /pkg_edit.php: [pfBlockerNG] XMLRPC sync terminated due to mis-configured Replication Target IP Address or Port settings.

Did you enter the port field? It will log that error message if the address is not valid (IPv4/6) or if the port is not valid…

Here is a snippet of that validation code:


        // Validate Replication Target IP Address and Port Settings
	if (!is_ipaddr($sync_to_ip) || !is_port($port)) {
		log_error("[pfBlockerNG] XMLRPC sync terminated due to mis-configured Replication Target IP Address or Port settings.");
		$success = FALSE;
		return $success;
	}

@jawz101:

For Reputation, 'Max', 'dMax' and 'pMax' are all individual settings.

'Max' is for each individual List, while the other two are done after downloading of the lists has completed. 'dmax' and 'pMax' Reputation processes analyze all of the lists as a collective.

@BBcan177:

Did you enter the port field? It will log that error message if the address is not valid (IPv4/6) or if the port is not valid…

Yep, and if I change the IPv6 address for an IPv4 one and change nothing else, it works without complaining. The logs show it is using the port - it just does not like a v6 address, with [] or without.
