PfBlockerNG v2.0 w/DNSBL
-
Hi Everyone,
I just wanted to share another source of feeds that you can pull in. Register for free at https://otx.alienvault.com. Once you get logged in start searching the pulses for ipv4 or domain etc to pull the lists you want. When you hit the download page click download, right click CSV; this is the feed you want to load into your DNSBL.
Also note that IOCs can contain file hashes and other types of data not useful to pfblockerng. In that case you can click "create pulse", copy the CSV feed you want to include, and follow the wizard through to remove any of the IOCs that cant be read by pfblockerng.
Edit: Ah nevermind, these don't parse clean
local-data: "'domain','akamaitechnologysupport.com','' 60 IN A 10.10.10.1"When BBcan177 return from vacation, he will look at this.

Is it possible to use DNSBL on a transparent firewall (none of the NIC's has an IP except for the Bridge itself (10.1.0.10))? I am asking because I tried and I can't seem to access the VIP at 172.16.15.14. I guess NAT does not work with bridges.. hmm, any help appreciated. I'd really like to use DNSBL! Thanks!

What are the choice available DNSBL Listening Interface ?
Did you look at the Firewall / NAT / Port Forward tab?

Did you look at the Firewall / NAT / Port Forward tab?My choice for the listening interface is LAN and BRIDGE. Tried both but no dice. The Port Forward tab lookes similar to yours (technically the same) when I enable DNSBL.
-
No clue, no bridge here.
Did you look at all posts in this thread and the pfBlockerNG thread to see if people had the same issues? -
Can you ping the VIP ?
Can you access http://172.16.15.14
Are all clients DNS using pfsense with DNSBL ?
Anything in the Systems Log or Firewall Logs, pfblockerNG log files ? -

Anything in the Systems Log or Firewall Logs, pfblockerNG log files ?Can't ping or access it. I think it's because bridges usually don't do NAT and I don't think that there is a way to create the functionality DNSBL needs (services on port 80/443). but without using NAT. Please tell me I am wrong. :)
-
I found a way to use DNSBL on my transparent bridge! :D
I configure DNSBL to listen on LAN at 10.10.10.1 as usual. But then (because I never get a reply from 10.10.10.1) I just reject all connections to "This Firewall" on ports 8081 and 8443.
I won't get any stats or 1x1 gifs but web sites load fast and without ads. :) -
Hey all,
I'm trying to set up PFBlockerNG with GeoIP to block everything apart from my country by only PERMITTING my country, rather than selecting everything apart from my country and blocking inbound.So under GeoIP i have selected <mycountry>under Top 20 and then Permit Inbound
This creates a permit rule under floating rules but i think im confusing myself as to what is happening here.
I have a web server running on the WAN, for which i have a WAN rule that permits any source to port 80 and 443. If there is a floating rule that allows UK IP's is that not allowing all UK IP's / Ports into my network? At what point does the float rule come into it?
What i want is for the firewall to check if the source is from the UK, if not block, then if its destined for port 80 or 443, if not block.
So under General - Rule Order should i select:-
pfB_Pass/Match | pfSense Pass/Match | pfB_Block/Reject | pfSense Block/Reject
or (leaning to this one)
pfSense Pass/Match | pfB_Pass/Match | pfB_Block/Reject | pfSense Block/Reject
Thinking it will match on 80 or 443 then match on UK.
Or something else, am i going about this the correct way? I kind of expected a blocking rule somewhere for ! <mycountry>Sorry - getting my head in a right pickle here. ;D</mycountry></mycountry>

Then you can install or re-install the pfBlockerNG 2.1.1_2.
The install should update the MaxMind (this take 5+ minutes) and proceed to completion. -
hi all,
i have performed this change, still the pfBlockerNG is not seen anymore in gui.
anyone had this before? -
Where does it fails when you install it ? There must be some hints in the installation logs, system log or pfblockerng log.

This tells me you only have 100M for memory limit.
What are the fixes you applied up to now to the system? -
/usr/local/pkg/pfblockerng/pfblockerng.inc
pfb_global();
// DNSBL Lighttpd HTTPS Daemon (Scans Lighttpd dnsbl_error.log for requested https domain names)
if (isset($argv[1]) && $argv[1] == 'dnsbl') {
set_time_limit(0);
pfb_livetail($pfb['dnserrlog'], 'dnsbl');
exit;
}and i guess is default.
and also usr/local/www/pfblockerng/pfblockerng.php - not modified.
-
And no modifications to /etc/inc/config.inc or /usr/local/etc/php.ini, /etc/rc.php_ini_setup ?
-
well based on my comments i did one to the first file:
// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
ini_set("memory_limit", "512M");
} else {
ini_set("memory_limit", "256M"); # increased from 128M
}–--
-
This change only affect i386 systems, you are on a amd64.
Did you raise the System / Advanced / Firewall & NAT Firewall Maximum Table Entries ?
