PfBlockerNG v2.0 w/DNSBL
-
@Gé:
How can I make a whitelist for pfblocker or more for dnsbl?
I created a alias with 2 test domains and set it as the first floating rule but that didn't work the 2 test domains can't be reached.How do i do this the best way?
The IP rules are independent of DNSBL…
Currently, you can't create access-control type refinements in DNSBL. If you want to have some devices to bypass DNSBL, then those devices need to use a different DNS server. I have plans for improvement in this area, but that involves enabling python support in Unbound and designing a python script for DNSBL
-
Sounds complicated.
Good luck with this future improvement.Using a alternative DNS is a good enough solution to reach a site I can't reach thru dnsbl wen needed.
Thank you!

pfBlockerNG: DNSBL: Settings (Custom Domain Suppression) ? No ?

Hi yea,
When you hit "save" to update that DNSBL list, do you know if the pfBNG cron task might have been running in the background at the same time? Can you see the pfblockerng.log?
Hi BBcan177 nothing warned me of such. Couldn't prove either way I'm afraid.

I am seeing an issue where the pages with ads can take up to 20 seconds to timeout prior to loading the page…
Example: landsend.com will sit blank for 20 seconds waiting on assets.adobedtm.com, then loads immediately.
Our DNSBL webserver is set at 192.168.192.168 and i can ping it from my computer, it is also set to allow all traffic to/from this address in the floating rules.
My internal network is 10.0.0.0/12 and Guest network is in 172.16.0.0/16 range.
I have followed all the instructions in this forum, and all is working well, except this delay between DNSBL and the computer.
Are there any more tests i can do to check the connection to the DNSBL webserver? If I browse to the IP or request a jpg file it times out.
Thanks for any help or suggestions.

You have to check your Firewall/NAT rules to see if a rule is blocking access to the DNSBL VIP from your LAN. Without fixing that you will get timeouts as you are experiencing. You have to ensure that you can ping and browse to the VIP.

I have hard coded some domains so that they can't be suppressed ;) <kidding>Run the following command to see if the domain is in the DNSBL list:
grep "example.com" /var/unbound/pfb_dnsbl.confpinging those domains should also resolve to the DNSBL VIP address.
If the domain is listed there, then check to see if your device DNS is pointed to the Resolver, and is not resolving from to a different DNS server…</kidding>
if I ping the domains its resolve the DNSBL IP 10.10.10.1
now somehow stuff start working and it blocks the sites.
maybe it needed time ? I didn't change anything from side . -
I have posted a Pull Request #1223:
-
Fix 'Match Outbound' rule variable name
-
Remove duplicate Alexa variable as its already in pfb_global()
-
Determine if a DNSBL background reload is running before updating DNSBL
-
Change "${cmd}" variable name to "{$cmd}"
-
Add $pfb['ccdir'] explicitly due to file caching issue.
-
Fix dShield URL
-
Add tcpiputils to DNSBL Domain threat lookup
-
Add log size settings (5000 & 10000 lines) for limited storage installations. (Not recommended)
-

I have a question of running VPN next to/ together with DNSBL.
On my laptop and Iphone/ Ipad i have client software running PIA VPN. With the VPN on nothing seem to be blocked, when switched of DNSBL is working. This is confirmed in the alerts tab and log.
Is it not possible to run VPN and DNSBL ? My understanding of the system is still limited. Hope you guys could point me in the right direction.
Greets,

I don't personally use a VPM like PIA, but the only way for DNSBL to function, is if the pfSense Resolver is used for the DNS requests. If the VPN uses a different DNS server, then DNSBL will not block any domains…
-
Ok thanks for the reply.
Is it possible to use another DNS then the one from the VPN server to use both systems.
When i run the VPN and DNSBL the NTp clock syc & dns resoler go "off" and then nothing works anymore.

I think I understand the issue when running a PIA client on a device behind the pfSense system.
Does this issue exist if you use pfSense/OpenVPN system as the VPN client? If so, is the fix as simple as using PIA's DNS values in pfSense?
-
Using the DNS of the VPN server did not change the problem.
When i start running the Openvpn client "unbound" will stop together with the "ntp sync" internet. Running no client VPN everything runs well.
My goal is to run client VPN to PIA plus use the capabilities of pfblockerng dnsbl for ad blocking, trackers etc. In don,t want my IP to be shown.

Thanks for the information. This is the direction I'm heading too. I have a few more things to clean up before I (re)invoke my PIA connection. I'll keep an eye on your issue.

I have been dealing with this issue also, I have found using wireshark that the VIP network request is being sent to 10.10.10.1 on port 80 (not the port that you have set) so the website waits until it times out to load the page.
A previous post mentioned that it was squid that was sending traffic to port 80. (to see the 1x1 gif you need to go to 10.10.10.1 on the port you have set.)
I have also set the VIP ip to 172.16.0.5 and the ports to 8178 and 8179 (suricata off, squid off, squidguard off) using wireshark I still see traffic going to 10.10.10.1 port 80
Also on systems that do not use the squid3 have the same delay also on windows or centos. The websites I am using to test are newegg and foxnews.

Hi cmpufxr,
Check your desktop DNS settings, and make sure they are only pointing to the pfSense Resolver IP address. If you have a multi-segmented LAN network, make sure to add the DNSBL allow firewall rule to allow those other subnets access to the VIP address. Make sure you can ping and browse to the DNSBL VIP, without that connectivity working properly, you will see those timeouts.
Keep in mind that there are two NAT rules that forward traffic from the VIP address on ports 80/443 to the 127.0.0.1 DNSBL Port/SSL ports.

Dns settings are good, I have access to the VIP I can only browse to the VIP with 10.10.10.1:8178 and https:\10.10.10.1:8179 (vip address and port)
It looks like the NAT rule is not forwarding from 80 and 443 to 8178 and 8179.
Thanks, I have at least identified the issue, now to fix it.
I run a website so incoming port 80 on the wan is already forwarded. I also block all outgoing and have rules setup to allow 80 and 443 out on the LAN. I wonder if these are causing issues.
-
Ok, I found out the reason for why some websites were slow. ( newegg cnn fox landsend )
On my system I block all incoming and outgoing traffic on lan, vlan1, vlan2
When I setup pfblockerng with dnsbl I did not add the outgoing rules on the lan interface for both the dnsbl ip's.
So in the floating rule that I already had for outgoing system ports I added both the ip's for the dnsbl web server.
so the only traffic that was going out was the 80 and 443 and when the NAT rule tried to forward this traffic to 127.0.0.1 port 8178 and 8179 (this is also outgoing traffic from lan to 127.0.0.1) so I had to add 8178 and 8179 to my LAN outgoing port rules.
before the rule I could ping 10.10.10.1 but NOT browse to the 1x1 pixel gif unles I added the port (ie 10.10.10.1:8178). After I can browse and ping to 10.10.10.1 without having to add the port
I hope this helps someone else… Thank you for all your help
Thanks BBcan177 for getting me on the right track...

When creating the Alias are you add them into a larger group or are you leaving them as they are individual items? Is there a limitation on amount of alias you can add to a group?
Here are more DNSBL Feeds that can be used in pfBlockerNG.
(Copy and paste URLS as plain text)- Create a new alias for these.
These are not necessarily ADvert domains. So I named mine "Malicious"
