PfBlockerNG v2.0 w/DNSBL

Panja

Both IP Reputation and DNSBL achieve two different layer of protection.

What are the differences? I'm just curious.
I love your work btw! Great job.

Getting this EasyList error for w/o elements.

[ DNSBL_EasyList - w/o Elements ] Download FAIL
Could not determine IP address of host.
Firewall and/or IDS are not blocking download.

Well that's not a package error. You need working DNS. :D
$ host easylist-downloads.adblockplus.org
easylist-downloads.adblockplus.org has address 148.251.139.76
easylist-downloads.adblockplus.org has address 144.76.100.145
easylist-downloads.adblockplus.org has IPv6 address 2a01:4f8:200:114f::2
easylist-downloads.adblockplus.org has IPv6 address 2a01:4f8:192:7126::2
Filter out easylist-downloads.adblockplus.org via DNSBL as well as add it to an allow alias and see if this helps. Depending out how you having things setup could be blocking. Host lookup most likely works because it's doing is via unbound. Just a thought let us know :)

DNS is working fine. It downloads the "Privacy" list which is just after w/o Elements.

thanks for that - useful reading for anyone thinking about using DNSBL.

Where can i find the list referred in your post.

"See the script that I wrote to add over 50+ different blocklists for IP Reputation."

Thanks

Is the 'Header' set as "w/o Elements"… Don't add special characters or spaces... just call it "EasyList" and the other "EasyPrivacy" as the Header/Label. Did you configure the Categories for both lists? In the latest version 2.0.1, there is a fix which might help diagnose this issue for you.

@michaelmullanyza:

What's the point in using the DNSBL then? I understand if I want to block the domain "facebook.com" I can do that with DNSBL, but if I'm only really making use of iblocklist.com and your bambenekconsulting lists, there's no need for me to make use of DNSBL correct?

There are several other lists the perform better than IBlock lists. They have too many false positives. See the script that I wrote to add over 50+ different blocklists for IP Reputation.

Both IP Reputation and DNSBL achieve two different layer of protection. Not too mention that DNSBL also properly handles ADvert blocking.

Had same issue. I tried to start it by pressing restart on dashboard, but no joy. But when i ran in console "/usr/local/etc/rc.d/dnsbl.sh start" it started service, but continue to load command prompt in web browser forever, so i got no output.

Finally server started and i got data at logs.

Many thnx :)

When you were at the Dashboard: Services Status Widget, if DNSBL was not running, it would have shown a red "X" and a single "Start" Icon". The "Restart" Icon is only visible when the service is already started? Can you try to stop/start the DNSBL service from the Dashboard? I can't duplicate this issue?

Removing "w/o" has fixed this. Thank you!

mine fault, it was only start which was doing nothing. Alsop nothing at system logs. Now, i tried to actually restart and works fine now.

Cheers :)

PS. At first post i wanted to quote this, sorry:

Checklist:

pfBlockerNG enabled in General Tab
DNSBL enabled in DNSBL Tab
VIP, port and ssl port defined in DNSBL Tab
DNS Resolver enabled

Then run a 'Force Update'. If it still doesn't start, execute the following and see if it shows any additional info:
Code: [Select]

/usr/local/etc/rc.d/dnsbl.sh start

I was thinking about using the new features of pfBlockerNG 2.0 to stop spam at the firewall since the current version of PostFix does not yet support DNSBL out of the box…
I was thinking of setting the list action to alias, then putting the firewall rules in to block all incoming from the sites. Problem I think is that the SpamHaus DNS list is a live list (query).... Is this supported?

Panja

I have installed pfBlockerNG v2.01 on my APU1D4 pfSense 2.2.5

I'm blocking a few countries for inbound traffic.
I also setup DNSBL as per post: https://forum.pfsense.org/index.php?topic=102470.msg572943#msg572943

I'm using OpenDNS in General Setup and DNS Resolver is enabled with the following options:
Enable Forwarding Mode (this is needed for my OpenDNS filtering)
Register DHCP leases in the DNS Resolver
Register DHCP static mappings in the DNS Resolver

All is working, ads are being blocked.
Only problem is when I reboot my box the Unbound Service is not started automatically (or is being stopped).
So with every reboot I do, I have to manually start the Unbound Service.

What could be the problem?

You lost the pfb_dnsbl.conf, in Unbound(Advanced) conf, due to /var in RAM ?
Delete that line and do a pfB Force Update.

Panja

Nope… The line was there:
server:include: /var/unbound/pfb_dnsbl.conf

But I removed it, did a force update and rebooted.
Same problem.
Unbound is stopped when the reboot is done.

BBcan177

Try to set the Resolver without the two DHCP registration checkboxs enabled… See the first post in this thread :)

Panja

I have read that post. :)

Disable the two "DHCP registrations" checkboxes, unless you really require those options.

I really require those, thats the reason I left them checked… 8)
Will uncheck them and check if it fixes things for me.

Panja

It indeed works now. ;D
I will leave the two checkboxes unchecked and live without them.

Btw many thanks for bringing this awesome package to us BBcan177.
Much appreciated!

@BBcan177:

This warning indicates that the masterfile is out of sync with the files in the /deny folder. This is a new feature that was added to v2.0 to warn users about this issue. Usually running a 'Force Reload' is sufficient to fix that warning; however, clearing out all the files and starting fresh might be needed in certain conditions. If this is still an issue, please review the pfblockerng.log file for other clues.

Re-installed and re-configured from scratch, nothing helps, the warning is still there.
No error in the log.
/var/db/pfblockerng/deny is empty (I have permit aliases only).

Panja

I'm having another problem.
All is working on my LAN interface but I have created a WIFI_GUEST interface.
On the WIFI_GUEST interface it's not working. Some sites won't load at all.
I have checked the floating rule and both interfaces (LAN + WIFI_GUEST) are checked.

WIFI_GUEST firewall rules:

Jamerson

Thank you so much,
any suggestions how to configure this ?
on the list of action, have to use disable or deny inbound ?

I've configured deny inbound and enabled alexa list but the webserver isn't starting at all
pfBlockerNG DNSBL Web Server is not started yet .

what I am doing wrong ?

You need a rule interface WIFI_GUEST interface source WIFI_GUEST net destination 127.0.0.1ports 8081 8443 so dnsbl can work.
