PfBlockerNG
-
@Mr.:
Thank you for the package much appreciate it .
after applying the settings on the pfBlockerNG my internet stops working,
i've followed this video for the setup but after i enable pfBlockerNG the internet stops workinghttps://www.youtube.com/watch?v=vgM5JRo575UI scrolled through that vid but, and sorry to sound like I do ( ;D ) but that is the usual useless non-tuto, of which you can find a zillion; they never even show it works. They'd better of going out walking the dog than wasting their - and all the other populants of this earth - time.
That aside: do you have any floating rules generated in the firewall? What do your firewall logs show you?
Your much better of reading this (yes, long, I know :-[ ) thread, where BB has added tons of information.
If you don't want to waste so much time reading this thread, remember this: BB wasted his time answering in this thread ;D
[/quote]thank you for your answer.
there is no particular firewall rules to block the internet. everything works fine untill the pfblocker is activated and stops things working. -
@shadowset:
I have a couple questions:
Can PFBlockerNG work with lists in p2p.gz format? I didn't see it listed in the IPv4/IPv6 tabs.
Also can PFBlockerNG use snort lists for IP blocking?
Thanks.
Can you link me to the .gz list in question?
Yes pfBlockerNG can use snort's IP lists
i am having the same issue can't get the internet working after the pfblockerNG is enabled.
Firewall rules from the LAN are allowed to everything,
from the WAN is as usually allowing the OPENVPN.Do you have OpenVPN Interface selected from the General tab in pfBlockerNG ?

no i don't have openvpn interface selected
on the Interface/Rules Configuration
i have inbound firewall rules and outbound firewall rules.
inbound = WAN Action Block
outbound = LAN Action RejectThank you

pfBlockerNG Firewall 1.09
2.2.3-RELEASE (amd64)
FreeBSD 10.1-RELEASE-p13Hello,
I am using custom inbound IPv4 lists (spamhaus, DShield, etc) set to Deny_Inbound with a custom port alias set up. When I look at the alerts, it shows entries for ports that I do not have specified to block.
My alias smtp_ports has the value "25, 465, 587" and I see Alerts like this:
Jul 12 05:27:36 WAN pfB_DShield
(96) TCP-S Icon Reverse Resolve with DNS 94.102.52.27:49717 my_server_ip_here:902 NL dshieldObviously port 902 is not within my alias parameters, so I am thinking something is wrong here. Either it is truly blocking all ports from the IPs on the lists and ignoring my specified ports, or it is just showing false alerts.
Please advise.
Thank you!

When using "Adv. Inbound Settings", you need to set the "Custom Protocol" setting. If you use "any" it will act on all ports, suggest to use "TCP/UDP" or as required.

Thank you, I've set custom protocol to tcp/ip for all of my ipv6 lists and top25. Seems odd to me that is a requirement.
Thanks again! I will report back if I encounter any other issues.

Did that fix your problem Jamerson?
no still waiting for some answers,
whenever i activate the pfBlockerNG the internet stops working. -

Just wanted to add, also having issues with pfBlockerNG, but only after a reboot. Which just noticed, because the UPS needs new batteries. Power here is terrible and has gone out several times. Each time after pfSense reboots can not connect to the internet and sometimes even to pfSense.
Guessing this a new issue, since did not notice this before. Either with the recent change to pfSense made with the 2.2.3 update or with the pfBlockerNG 1.09 update. Both happened about the same time. Before those updates everything worked fine, but had not rebooted since the 2.2.2 update. So it is possible that is not the cause.
After connecting to pfSense and unchecking the Enable/Disable checkbox[to disable] and then saving; internet comes back up. After that checking the Enable/Disbable checkbox[to enable] and then saving. And forcing an update, cron and reload; pfBlockerNG works fine after that.
Note, if it matters: the few times I remembered to ping a site[7) Ping host], did not get any packet loss. Before doing the above. Also the Floating Rules are present before doing the above.
Using the defaults for many of the options and just have a few IPV4 lists. Nothing shows in the logs that would be helpful.
Thanks

Hi cyberbot/taryezveb,
Are you running a Nano version/Ramdisk or a full installation of pfSense?
On reboot is there a delay in the Reboot process? ie - Stuck on "Loading Firewall … " in the pfSense boot console screen?
After pfSense Boots, does the widget show entries in the packet column? or is it all blank?
When you hover-over the Firewall Rules for pfBNG, does each Firewall rule popup a table showing the IP addresses?
Run the following commands when there are issues, and report back with the output.
/sbin/pfctl -vvsTables | grep -A4 'pfB_'
ls -lah /var/db/aliastables/* -
Is it appropriate to offer a bounty here?
I'd like to pledge $100 to add the following feature: block TOR exit nodes. I personally like TOR, but my forum is getting attacks from the TOR network that average more than one every eight seconds. Right now I'm going to the following URL and manually updating the list of nodes that can access my site as a custom list:
https://check.torproject.org/cgi-bin/TorBulkExitList.py?ip=[my server's IP address]&port=
I'd love to be able to simply check TOR the way I can flag a country within pfBlockerNG to deal with the problem instead.

It's always appropriate to throw beer or coffee to BB ;D
If you are in a hurry, I noticed, for me Snort/Suricata are also blocking TOR nodes. So you could perhaps use that until (and if) BB finds time to fulfill your request.

There are three IP lists that contain 'Tor Exit Nodes' that can be used in pfBNG without any code changes :
(gz) http://list.iblocklist.com/?list=togdoptykrlolpddwbvz&fileformat=p2p&archiveformat=gz

Thanks for that BB. I'd been trying https://www.dan.me.uk/torlist/ and was seeing Download FAIL messages. I'll tinker a bit more.

Hi cyberbot/taryezveb,
Are you running a Nano version/Ramdisk or a full installation of pfSense?
Full install here.
On reboot is there a delay in the Reboot process? ie - Stuck on "Loading Firewall … " in the pfSense boot console screen?
None that can recall. pfSense boots normally, will verify again tho. Once the new monitor arrives, since the previous one failed and do not have any at the moment. Not much luck with hardware lately :)
After pfSense Boots, does the widget show entries in the packet column? or is it all blank?
It is all blank, will verify again tho.
When you hover-over the Firewall Rules for pfBNG, does each Firewall rule popup a table showing the IP addresses?
Will report back on this, did not think to try that.
Run the following commands when there are issues, and report back with the output.
/sbin/pfctl -vvsTables | grep -A4 'pfB_'
ls -lah /var/db/aliastables/*Will do. Not sure when I can report back, whether forced by power outage or just by rebooting. Need to find the right time to do this, if not forced too. Some people here complain when they can not connect to the internet; I'd rather avoid that if possible ;)
Also having another issue with an alias, that fails to load. Do not think this is the cause of or related to the reboot issue. Since pfBlockerNG keeps on working regardless after it is restarted as explained before. Can supply some details of that now or would it be better to deal with one issue at a time?
Thank You

Thanks for that BB. I'd been trying https://www.dan.me.uk/torlist/ and was seeing Download FAIL messages. I'll tinker a bit more.
For this particular list I ended up setting a cron job on one of my RaspberryPi's to fetch the list on schedule and then fetch it from the Pi to pfBlockerNG.

BBcan177,
A reboot was forced on me; power went out again :) So can answer some of your questions:
On reboot is there a delay in the Reboot process? ie - Stuck on "Loading Firewall … " in the pfSense boot console screen?
Can not answer this for sure, still have no monitor. Like said before do not recall any such issue.
After pfSense Boots, does the widget show entries in the packet column? or is it all blank?
Can verify, all blank.
When you hover-over the Firewall Rules for pfBNG, does each Firewall rule popup a table showing the IP addresses?
All blank as well.
Run the following commands when there are issues, and report back with the output.
/sbin/pfctl -vvsTables | grep -A4 'pfB_'
ls -lah /var/db/aliastables/*Here is the output of both commands, before restarting pfBlockerNG:

Updating: pfB_TBG
no IP address found for /31pfctl: cannot load /var/db/aliastables/pfB_TBG.txt: No error: 0Hi taryezveb,
What lists are in this pfB_TBG alias? Can you send me the full URLs that are part of this Alias? It seems that the IP parser failed to convert one line as it is showing "no IP address found for /31" and pfctl is failing. IBlock lists are renowned for adding strange IPs and once i review the list, I can patch this up.
It would be good if FreeBSD pfctl had some error checking ability. As any error in the alias file can cause the whole packet fence to fail.
If you see this issue again, please copy the /var/db/aliastables/pfB_TBG.txt file and forward to my email address which is in the General Tab of pfBNG. I would need to see the file before you perform a Reload.
Thanks!

Thanks for that BB. I'd been trying https://www.dan.me.uk/torlist/ and was seeing Download FAIL messages. I'll tinker a bit more.
For this particular list I ended up setting a cron job on one of my RaspberryPi's to fetch the list on schedule and then fetch it from the Pi to pfBlockerNG.
Its strange that you guys are seeing errors in downloading this list from www.dan.me.uk?
If you load that URL in a browser does it fail to download also? Did you try http instead? I use this list in several other boxes and have not seen anyone else complain about that list.
