PfBlockerNG v2.0 w/DNSBL
-
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.

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.
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? -

Which DNSBL Blocklists are you using? There are two posts in this thread for multiple DNSBL lists.
Are you sure that your LAN devices are not using a different DNS server?
Which sites are showing ADs?

Then in DNS I removed all forwarders and replaced it with 10.10.10.1.
Point your local LAN devices to your windows Server, and set the MS DNS forwarder to the pfSense IP Address to have DNSBL filter the DNS requests.

I went back and did what you said. LAN devices point to the windows server and the MS DNS forwarder was set to the pfsense LAN interface IP. DNSBL did not filter. I troubleshot it and got it to work by using the pfsense WAN interface IP. While everything is working now with DNSBL filtering traffic, I can't ping the LAN interface IP or access the webgui when on the LAN subnet. I enabled logging on the firewall and tested sending a PING to the pfsense LAN IP and here is what I get:

Maybe DNSBL was not filtering because the DNS on your Windows server cached the domain name ip before the switch.

I went back and did what you said. LAN devices point to the windows server and the MS DNS forwarder was set to the pfsense LAN interface IP. DNSBL did not filter. I troubleshot it and got it to work by using the pfsense WAN interface IP. While everything is working now with DNSBL filtering traffic, I can't ping the LAN interface IP or access the webgui when on the LAN subnet.
I would start by disabling DNSBL and fixing one issue at a time. You should be able to ping and browse to the pfSense LAN IP from any LAN device first before attempting to use any package. Always best to troubleshoot with less obstacles. Then once the basic connectivity is working, you can add additional features. Using the pfSense WAN IP in a local Windows Server DNS Forwarder, doesn't look to be a solution.

Can anyone help me figure out how to get rid of this?
I got pfblocker running and all setup. But when it blocks stuff I get this big error image.
When I try to go to the domain it shows in the alerts I get that 1x1 image. Why isn't it applying it to the page?

DNSBL pushes a 1x1 pixel image for any blocked domain. So if your viewing a page with ADverts, the Blocked AD is replaced with a hidden 1x1 image so that you don't see a big blocked image. But if the whole site your visiting is blocked completely by DNSBL, you will see the image that you show. Its a normal behavior.

Thanks! I stripped down everything to just a basic install and one by one added the necessary settings. Now it is working properly. Workstations point to the windows server, and the MS DNS forwarder points to the LAN IP of my pfsense box. It's all working properly for this remote office now.

Hi everybody,
I need some help with pfBlockerNG and squid on the same pfsense machine. (Additional packages snort)
I installed and configured the pfblockerng package, downloaded som DNSBL. Then for testing I pasted some of the URLs into my browser to test and then it redirects me to the pfsense WebUI but not to the 1x1 pixel web page. Further I do not get any Alert in the pfblocker alers tab.
I am not sure if it is relevant but I am running squid (http + https) on the same pfsense machine with Auto Proxy configuration configured on my client.
In pfblockerng I added 10.123.123.123 als the virtual IP. I do not use this IP or subnet somewhere on my network. When I enter 10.123.123.123 in my browser I am redirected to the pfsense WebUI. When I enter the NATed IP 10.123.123.123:8081 I got the 1x1 pixel picture.
My pfsense has two interfaces - one interface for WAN (192.168.178.0/24) and another interface for LAN (192.168.10.0/24).
So my questions are:
1. Why is it redirecting me to the WebUI when entering a URL / domain which ins in DNSBL instead of redirecting me to the NAted IP address with 1x1 pixel
2. When I use https://10.123.123.123:443 the connection times out, when I try to access https://10.123.123.123.8443 the proxy tells my "access denied".
3. No matter what I access I can see any alerts.I really appreciate any help and/or suggestions

Hi everybody,
I need some help with pfBlockerNG and squid on the same pfsense machine. (Additional packages snort)DNSBL adds two NAT rules to push the VIP 10.123.123.123 to 127.0.0.1 on what ever port you selected for DNSBL http/https.
I suspect that Squid is listening on localhost and interfering with DNSBL. I don't use Squid, so maybe some others will chime in on their setup…
-
Thanks,
but squid is listening on different port 3128 so there should be no problem - I think.
I am not sure if squid respects the NAT rules because my WebUI is listening on port 80 an when I try to access 10.123.123.123 I get the WebUI but no NAT/redirect to :8081
So I would be interested if there is someone who is using squid and DNSBL.
