PfBlockerNG v2.0 w/DNSBL
-
@bbcan177: I still have the issue that after pfsense has been rebooted with DNSBL enabled I manually have to start or restart the unbound service to get the DNS working. Any clue what cause this?
-
Hi fraglord, do you have either of the DHCP check boxes enabled in the Unbound Resolver settings tab? There seems to be some issues with those options. You can also review the pfSense System and Resolver logs for more clues.
-
Thanks for the quick reply :D I habe none of these options enabled because pfsense is not doing DHCP.
But there is something suspicious in the system logsphp-fpm[49122]: /rc.newwanip: The command '/usr/local/sbin/unbound -c /var/unbound/unbound.conf' returned exit code '1', the output was '[1456266101] unbound[78664:0] error: bind: address already in use [1456266101] unbound[78664:0] fatal error: could not open ports' -
It's not a DNSBL issue. Check your Unbound settings. Maybe an interface settings issue? If you don't resolve it, post in the DNS forum and see if anyone has other advice for you.

Firewall and/or IDS are not blocking download.I cant figure out what is going wrong in my settings. can somebody help me?
Thanks

When you see "403 Forbidden", the site that your trying to download from is either blocking your IP or rate limiting you. Disable the snort list for 24 hours and re-enable to get around that issue.
You can't use other EasyList feeds. Currently only two feeds for EasyList are hardcoded in the EasyList tab. There is also a note about this in the DNSBL tab.

Not sure if this is the cause of the problem - I am still investigating. At least I can confirm that with DNSBL disabled this problem does not occur.

How many domains are you blocking? You can see the total in the widget? Your footnote shows 1Gb of ram, maybe with DNSBL, it's taking longer for Unbound to start and newwanip is attempting to restart a second time? Can you increase the RAM size?

1099450 Domains in my case with 2.5GB

I can open the link in my browser, so i think they're not blocking me. I dont have the snort package installed on my pfsensebox. Which snortlist should i disable?
Thanks for the help!

Hi XmickS,
Sorry I meant to say disable the spamhaus drop list in pfBlockerNG for 24hrs. Typically a "403" error means the site you are downloading from is blocking you. Is your browser using a different Gateway or DNS server then the pfSense box? Do you use a proxy? If that doesn't help, post a screenshot of the spamhaus alias settings.

I'm starting from a fresh install of 2.2.6-RELEASE (amd64) and rebuilding to clear out cruft from multiple past upgrades.
The installation of the pfBlockerNG package has been sitting at "Executing custom_php_resync_config_command()…" for about 45 minutes now. The browser is not showing a loading animation either (shows the pfSense logo favicon).
Is this normal?
I'm on a 30 down/5 up connection. Whatever it's downloading, if it's downloading that is, shouldn't take that long. Diagnostics/System Activity doesn't appear to say a whole lot is happening on the CPU either.
-
Hi krhainos, can you post the last 20 lines of the pfblockerng.log? You can run this command from the Diagnostics: Command Prompt:
tail -n20 /var/log/pfblockerng/pfblockerng.log
Are there any relevant errors in the pfSense system log?

I'm actually on the way to figuring it out!
Something about one of my rules is tripping up the pfBlockerNG installation.
I've been keeping configuration backups after every piece I configure. I've only done restores from my old config on my alises list, and my rules. It seems the installation hangs after I restore my rules. I'll update once I figure out what exactly it dislikes about my rules.
Update: I found it. After going through the filter section in my config, I found a line between two rules that read "<rule>". It looked out of place, so I removed it. pfBlockerNG is happy now! It downloads, updates, crons and everything. I don't know how it got in there, and going through old backups, it's been there for a while.
I've attached a screenshot in case a visual helps.

Found the problem. I was using vpn client and the ip i was using was being blocked by spamhaus. when i switched to another ip i was able to download the list. now everything is working as (i think) it should. thanks for the help!

maybe a newbie question, but im curious. what is the difference with pfblockerng and adblock plus (or ghostery)? when these extensions are saying that they're blocking stuff, does that mean that my pfsense box is not blocking everything, or are they blocking the same stuff?
-
Adblock plus is an extension inside your Browser, so it does filter what your browser is using. It does not filter traffic for other application like Windows Update.
pfBlockerNG is on the firewall and filter traffic from all applications and computers.

But there is no difference in what they filter? Thought maybe pfblocker can't filter everything as well as an adblocker extension.
Sometimes an ad slips through my firewall. Does that mean I don't have everything set as it should?

Probably not… it just means the devious little bastards that foist their crap on us have found new inventive ways to sneak shit through. Give the list writers time, they'll catch up.

While I'm relatively new to PFBlockerNG, I've been reading up a lot so I don't ask a question that hasn't already been answered. I hope this is a new question.
I setup PFBlockerNG first at home to test and now I'm implementing it in my office environment (starting with a branch office so I don't disrupt everyone if something gets messed up). The issue I encountered is minor. My home setup utilized PFSense for DHCP and DNS, so the DNS Unbound receiver just worked out of the box once enabled. When testing the config on the Windows Domain network, I had some issues. Windows Server 2012 manages DHCP and DNS. DHCP was configured to set the DNS server as the local DNS server and a remote server (connected over VPN). DNS forwarders were set to point to multiple DNS servers (a few public ones provided by our ISP).
Once I got the settings setup at the office, I noticed no traffic in the PFBlockerNG Alerts. After redoing some settings, I removed all DNS servers from DHCP and set the server running DNS on the local subnet and 10.10.10.1 (set in DNSBL settings) as the other DNS server. Then in DNS I removed all forwarders and replaced it with 10.10.10.1. After completing this, everything was working with PFBlockerNG filtering out ads based on the lists I used from setting it up via this post - (https://forum.pfsense.org/index.php?topic=102470.msg572943#msg572943).
Now, everything seems to be working properly, but I noticed that within my local subnet (192.168.2.0/24), I am unable to ping PFsense or access the webgui interface using the internal IP (192.168.2.1). However, I am able to access the webgui using the public WAN IP (all over HTTPS). Also, when I am on the main office subnet (192.168.1.0/24), I can access the PFSense webgui for the remote office with the LAN IP over the VPN at (192.168.2.1) as well as by using the GUI.
I assume this is due to DNS but I am not 100% sure on how to resolve this on the local subnet. It's not a major issue as I can manage it with the WAN IP but if possible I'd like to be able to resolve this problem I've created. Any ideas?
TL;DR -
I configured PFBlockerNG, updated DHCP and DNS settings on my Windows Server 2012 box, and can only access the PFSense web gui via the WAN IP. Any ideas on what setting I am missing or did I mess something up?
