PfBlockerNG v2.0 w/DNSBL
-
pfBlockerNG v2.0.17 :
https://github.com/pfsense/FreeBSD-ports/pull/144This will fix the issue with the EasyPrivacy Feed (As noted above)
I suspect that EasyList will also change file formats at some point, but I will make those changes at that time.
Until the PR is merged, either disable EasyPrivacy, or fetch the file from my Github repo:
–> File below is only for pfSense v2.3.x <–
fetch -o /usr/local/pkg/pfblockerng/pfblockerng.inc "https://raw.githubusercontent.com/BBcan177/FreeBSD- ports/88fc815594c48f9d99c2f7feb9649a3586a3ca27/net/pfSense-pkg-pfBlockerNG/files/usr/local/pkg/pfblockerng/pfblockerng.inc"and run a "Force Reload - DNSBL"
Manually pulled the update and reverted my twitter.com whitelist. Did a force reload and can verify that the fix does work. Thanks.

Hi–
Firstly, thanks again for an awesome package!
I'd like to revisit an issue brought up numerous pages ago, that issue being that with pfBlockerNG and DNSBL enabled, along with the DNSBL Easy List to block ads, some web clients will throw an error like so:
Is this a Safari/Mobile Safari issue only? How are people working around this with pfBlockerNG? This issue is causing Wife Approval Factor to drop precipitously.
Thanks again,

Hi Paul,
Is this device on the latest Apple Software build? Is Safari updated?
Two other options.. 1) Install Chrome 2) Set the DNS setttings for this device to a different DNS server, so that it bypasses DNSBL.

Hello BBcan177–
Thanks for your reply--much appreciated.
All our desktops/laptops/devices are up to date running the latest: Safari 9.1.1 and OS X 10.11.5 on the desktop. All iPhones and iPads are running the latest as well.
Getting folks in the family to use another browser won't go very far :( Such is the life of the family sys admin.
Regarding:
- Set the DNS settings for this device to a different DNS server, so that it bypasses DNSBL.
All devices are using pfSense for DNS (forwarder is enabled).
If I'm understanding this issue correctly, these certs are all delivered via https. Since these connections are blocked by the EasyList, Safari throws these alerts?
Is this a known issue with Safari, or is there some configuration available that I'm not aware of?
thx

Hello,
I had pfblocker working fine on my other setup, but now since i upgraded to pfsense 2.3 my config was currupted and i had to do a clean install.
my problem with pfblocker is that i cant get the dnsbl to block ads. i configured the standard list(cameleon, yoyo, adaway enz.) and i also see a lot of ads listed in the alerts tab, but the ads still show up. i'm guessing the problem is with unbound. also when i do al update/reload, it says "Reloading Unbound … Not completed." see below.

Sorry if this is stupid question. I am using OpenDNS and wondered if I can use DNSBL along with it? The only way I was able to get alert data was by changing the DNS settings on my PC.
Not in this way. If you point your clients to pfSense as DNS server and use OpenDNS as forwarders for Unbound, then yes it should work.
I recently installed pfblockerng v2.0.17 with the help of https://m.youtube.com/watch?v=YLhDOaH0q5U and until then I used opendns. Is it possible to combine these two and if so how can I accomplish this and what could/would it bring.

It can be done just as Dok said above:
Point your LAN devices to pfSense Resolver/DNSBL, and then set the Resolver into "Forwarding mode" to the opendns servers… But keep in mind that opendns doesn't support DNSSEC, so disable those options...
-
Thanks for bringing us pfBlockerNG! As I am fairly new to the use of an ad blocker in combination what a firewall, can you be a bit more explicit say idiot proof ;) on the how to using pfBlockerNG and opendns?

Stupid me, that was easy (one check mark and one off). But when using the "Forwarding mode" am I not losing DNSBL and so a lot off "power" of your adblocker? In your professional opinion am I now penny wise and pond foolish?

Hi XmickS,
If you are using the Resolver in "Forwarder" mode, make sure that the DNS servers you are using support DNSSEC… This looks like a Resolver settings issue to me...
-
It can be done just as Dok said above:
Point your LAN devices to pfSense Resolver/DNSBL, and then set the Resolver into "Forwarding mode" to the opendns servers… But keep in mind that opendns doesn't support DNSSEC, so disable those options...
Stupid me, that was easy (one check mark and one off). But when using the "Forwarding mode" am I not losing DNSBL and so a lot off "power" of your adblocker? In your professional opinion am I now penny wise and pond foolish?
DNSBL has nothing to do with either "Forwarder" or "Resolver" mode in Unbound… Its a preference... But best to use "Resolver" mode as you are using the Root DNS Servers for the DNS requests...
Here is a good primer about the DNS Resolver (Unbound) https://calomel.org/unbound_dns.html

Hi BBcan177,
I had unbound in forwarder mode. When I go to a domain which is in one of the dnsbl feeds I get the 1x1 message so that tells me that there is something being blocked. when i open, for example yahoo.com, I can see al the boxes where the adds come in just not the contens of them. I'm not sure if on my previous pfsense box the whole ad was being blocked, like my adblocker does.
Is pfblocker capable of blocking this whole add thing or is it someting I didn't remember correctly?
Thanks for the help!

Yahoo, is doing something dirty with ADs on that page… Its actually an Image… So it can't be blocked by DNSBL since, its not doing a DNS resolution to an AD server... Right-Click on the AD then click "Inspect" ... You will see that its actually an Image.... I haven't seen this elsewhere except for Yahoo...

https://twitter.com/x0rz/status/739807696568918016allright… I think I see the same thing on aol.com. They just find another way to serve you ads. But with an adblocker on my browser and dnsbl blocking ads on mobile devices, I haven't seen them yet. So thats a good thing! Gonna donate right now. Thanks for making browsing a lot cleaner! ;D
Just one thing I can't get done. Thats blocking those annoying ads on youtube. Is that possible with dnsbl? I use the easylists Cameleon, adaway yoyo and hostfile. I haven't configured ip blocklists yet.

Does pfblockerNG2.0.4 need the localhost (127.0.0.1). As in the general setup of pfsense there is the "Disable DNS Forwarder" option! checking it and so disabling it removes 127.0.0.1 from the ISP DNS servers on the WAN in the Status -> Interfaces
(Do not use the DNS Forwarder as a DNS server for the firewall By default localhost (127.0.0.1) will be used as the first DNS server where the DNS Forwarder or DNS Resolver is enabled and set to listen on Localhost, so system can use the local DNS service to perform lookups. Checking this box omits localhost from the list of DNS servers.)

If you are using the Resolver in "Resolver mode"… then best to leave that option unchecked... This way, all requests goto the localhost for DNS resolution.
