PfBlockerNG v2.0 w/DNSBL

trinidadrancheria

Installed, It stopped at the same place as most others, being lazy I refreshed which reinstalled it again :D (3 less clicks than packages/reinstall/confirm) :P

Working GREAT! Gonna enable DNSBL for INBOUND Monday (using Alias) :)

Here is a PR to fix the Installation issue being reported…

https://github.com/pfsense/pfsense-packages/pull/1189

Once this is merged, if anyone has similar issues, please report back. Thanks!

If you move your configuration from DNS Forwarder to DNS Resolver in order to use pfBlockerNG: For multi-WAN configurations you have to have forwarding mode enabled. See also here: https://doc.pfsense.org/index.php/Unbound_DNS_Resolver

Hugovsky

Thanks BBcan177, and everyone that made this package possible. Great jpb.

Can you elaborate? I have multi-wan and forwarding disabled and everything works.

@BBcan177:

There are several other DNSBL Feeds that can be used with pfBNG DNSBL. I will post that at a later date, once users get their basic configurations working. There is also an ADBlock Easylist tab, which is pretty self-explanatory.

Huge thanks BBcan177!!! First off really looking forward to you posting more feeds, more importantly though where can I donate? I'd like to thank you, you have no idea I've been trying to block ads on my wireless devices and had been trying to do this on an Asus RT-68U (AP mode) with both tomato and merlin and was having issues. PfBlockerNG 2.0 has solved this issue for me, I no longer have to mess around with the Asus router and don't have to worry bout getting ads on my sons ipad/pc. I added a feed from http://winhelp2002.mvps.org/hosts.htm would this work for host files as well? In the log it does seem to have downloaded the .txt file (see attached screenshot) Thanks again BBcan177 for your work!

BBcan177

Here are more DNSBL Feeds that can be used in pfBlockerNG.

@BBcan177:

Here are some basic instructions to get started with DNSBL.

Open the pfBNG "DNSBL" Tab:

(Use the defaults unless you have a need to use otherwise)
Enter the DNSBL VIP as 10.10.10.1
Enter the DNSBL Listening Port as 8081
Enter the DNSBL SSL Listening port as 8443
Select the DNSBL Listening Interface as Lan

For the DNSBL Firewall Rule select all of the LAN subnets that access the DNS Resolver.
Ensure that all Devices that use the DNS Resolver, have the Resolver as its only DNS setting for DNSBL to function properly.

DNSBL IP Firewall Rule Settings:
Select Deny outbound or as per your requirements
select Enable logging

Alexa (is optional, you can skip this until later if you wish)
Select Top 1K
Select the TLD Inclusions as ca,co,com,io,me,net,org or as required.

In the Custom List you may enter any domain you wish to Whitelist.

Save your settings

Open the "DNSBL Feeds" Tab:

Create a new DNSBL Alias

Enter DNS Group Name as ADs
Enter Description as DNSBL ADverts

DNSBL:

Enter the Header/Label and Source URL as follows:
(Use copy/paste as plain text for the URL)

Format Auto and State ON

yoyo
http://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&mimetype=plaintext

hpHosts_ads
http://hosts-file.net/ad_servers.txt

Adaway
https://adaway.org/hosts.txt

Cameleon
http://sysctl.org/cameleon/hosts

Select List Action as Unbound
Select Update Frequency as Once a day

Alexa:
Do not enable the Alexa Whitelist for this ADverts based alias, as Alexa also posts the top ADvert servers. So using Alexa whitelist, will interfere with ADvert Blocking.

Add any other domains that you wish to block in the Custom List.

Save your settings

Open the "DNSBL" Tab:

Click DNSBL Enable checkbox.
Save your settings

Open the "Update" Tab:

Select Force Update

You should now see the DNSBL Feeds being downloaded and parsed. Once that is complete, goto the Dashboard, and confirm that the widget is populated correctly.

Goto the pfBlockerNG "Alerts" Tab:

Any domain that is blocked will be reported here. For HTTPS alerts, the SRC IP and URL are not captured due to Browser security measures.

As a test, goto www.aol.com and www.yahoo.com and see some alerts populate.

There are several other DNSBL Feeds that can be used with pfBNG DNSBL. I will post that at a later date, once users get their basic configurations working. There is also an ADBlock Easylist tab, which is pretty self-explanatory.

Have been using the beta code for some time and noticed a list of domains in the Alexa top 1K that serve up ads, since I don't want this I added the following custom block list to my Ads DNS Group which will remove them from any DNS group that is using the Alexa top 1K filter.

To confirm make sure "Enable Alexa Whitelist" is NOT checked for this DNS group.

Thanks again BBcan177 for your work!

I could use a lifetime pfSense Gold subscription… :) But I think all developers should get that as a bonus :)

My email is at the bottom of the pfBNG general tab.

:o lifetime ? That would be $99 x how many ever years you have left ;D :P so is the email there attached to a paypal account? Not sure if donation talk is allowed on forum if not, I apologize mods. Also , It does seem to be working for host files from http://winhelp2002.mvps.org/hosts.htm Thanks!

fraglord

Can you elaborate? I have multi-wan and forwarding disabled and everything works.

If you enable forwarding mode then a foward-zone named "." is created as well as some forward-addr entries with the DNS servers you sepcified system->general setup.
Default behavior of unbound is to query the Root servers. But if you have a multi-WAN configuration and need to specifiy a different DNS server for each WAN(gateway) you need forwarding mode to be enabled. So yeah, works without forwarding mode for some multi-WAN configs that are fine with just the Root servers.

vito

BBCan177,
Any problems running your list import script on PFB 2.0?

tonymorella

Few things I found out while beta testing V2

First rule is take your time and be patient. Adding to may rules at once will casue alot of blocks you may or may not way. Wildcards are not supported, or wanted in most cases. For example adding google.com does not filter all the hosts for the domain, need to add each host that is being blocked to the filter lists
Make sure to double check ASN's, especially for large companies that have acquired other companies, more than one ASN might exist
*** Unbound has an issue in my setup using OpenVPN connected to PIA. It does not start correctly when a network issue is sensed, em1 or openvpn interfaces flap for example. The core problem seems to be how the rc scripts handle unbound reload. They do a HUP vs reload to get around the cache being lost. Disabling "DHCP Registration" or "Static DHCP" was a workaround that allowed unbound to start correctly.
Checking "DHCP Registration" or "Static DHCP" causes other issues with unbound, this is a know issue being talked about in the DNS forum. I added all my hosts host to unbound statically as a work around
I wanted to have my allow rules > pfb block rules > my block rules > my per interface rules. Did this by enabling "Floating Rules" and using "pfb_pass/match | pfsense pass/match | pfb_block/reject"
If you have WIFI make sure to enable "DNSBL Firewall Rule" and select both LAN and WIFI or the NAT: Port Forward rule for 10.10.10.1 is not setup correctly. If you don't change this setting things still work but everything runs slow over wifi.
Make sure to whitelist all the DNSBL sites FQDN via an allow aliases, some IPv4 block-lists include the IP space the DNSBL are found in
DBSBL is basicly a man in the middle for DNS so any site that is block but running https will create warrnings. Depending on how the brower is setup it might just ignore or not display the error. CTRL+SHIFT+I on both Chrome and Firebox will bring up dev panel where you can see which pages are not loading. Chrome will show an error, Firefox will show a red slash throught the lock icon.
Noticed a list of domains in the Alexa top 1K that serve up ads, since I don't want this I added the following custom block list to my Ads DNS Group which will remove them from any DNS group that is using the Alexa top 1K filter. To confirm make sure "Enable Alexa Whitelist" is NOT checked for this DNS group.

This scripted worked without an issue for me.

Oops! I found ZeuS Tracker is shut down, I hope it is only temporary.

I am receiving certificate invalid errors after enabling the DNSBL when navigating certain sites - so far the culprit seems to mainly be googleads.g.doubleclick.net when trying to serve content over an HTTPS enabled website.

The attempt still shows in the Alerts tab of pfBlockerNG, the main site still loads, but it seems to be wanting to use the firewall's self signed certificate as the certificate for the ad server host.

Did I miss a setting somewhere to prevent this from happening?

doktornotor

There's no such setting anywhere and no way to prevent this from happening really, except for whitelisting the domain.

reggie14

@Atlan

To a certain extent, this isn't surprising. pfBlockerNG essentially has to Man-in-the-Midde HTTPS. If the ad is being loaded from an HTTPS server (I don't necessarily mean the page you're viewing, rather where the ad itself is coming from), then pfBlockerNG redirects you to its own little webserver running on your pfsense box, and, since is done over HTTPS, that webserver uses a generic, default certificate. It's a different cert than what is used for the pfsense WebGUI. For various reasons, pfBlockerNG uses the same certifcate for every blocked HTTPS resource. This creates a problem because the name in the certificate doesn't match the domain name of the blocked resource, which is why you see certificate warnings. There's no good way around this, though. Attempting to dynamically create valid certs off a CA running on the pfsense box would be both complicated and slow.

But, I'm a little surprised you're seeing warnings. I used to see warnings occasionally, but I haven't for a while. I thought browsers just started silently dropping HTTPS connections to external resources when there's a bad certificate.

Can you provide additional information to reproduce this? What browser are you using? What webpage were you accessing? If I can see an example, and maybe inspect a packet capture and page source code may be I can see what's going on.

MBwork

What about setting your virtual address to 0.0.0.0? As that whole /8 is non-routable, you wouldn't get the cert error. It would just silently fail to load ads.
