PfBlockerNG

vwgti

I'm trying to whitelist access to a website behind my firewall to my own country only.

When I create a Country list action as an 'alias permit' then use the resulting alias as the Source for the existing website NAT rule, it breaks my internal network access to the site. NAT Refelction is set to Enable (NAT + Proxy), what am i missing here?

I am starting to get errors. I guess the lists i am using are old. Where do i get the new list?

You can change the Lists state to FLEX for those lists and see if this help.

PfBlockeNG sounds really great, but after reading through about 500 posts I found a few people requesting a shorter tutorial, but no one has responded to those request.

Is there a concise guide to setting up and configuring PfblockerNG 2.0.4? I could eliminate a lot of repetitive questions.

I'd rather learn from the mistakes of others, than stay up to 2am trying figure out what setting I goofed.

Thanks

Converting MaxMind Country databases for pfBlockerNG.
This may take a few minutes…

I just did fresh a install of pfSense after using the box for other stuff for a while and the converting the database process just hangs. It didn't a few months ago. I was running 2.2.5 the last time I had installed pfB so that and whatever has changed with the addon since a few months is really the only things that have changed in the process.

This is a fast 50+MB connection and an Intel c2758 board so I can't think it's the equipment. Logs aren't showing anything funky. I've removed and reinstalled pfB a few times to see if something would change but the CPU is idle at this point and logs aren't indicating anything's going on at this point of the install. I let it go about 20+ minutes on one attempt and just now let it sit there while I slept 7+ hours.

I can clearly see the lists have downloaded to the box via ssh and I even looked at the github source and downloaded the country lists from the url's via my browser.

edit- just redownloaded the pfSense iso, verified hash, reinstalled pfSense and still get the same hang

@BBCan17
I've since reinstalled Firefox and started walking through all of my addons setting them back up how I had them. So far I haven't seen it not install now. Maybe either successfully installing it once from another browser is what fixed it or I haven't checked a setting in my add-ons that was causing the error or maybe something in my browser cache… no idea. Kinda frustrating I haven't pinned it down but at least it wasn't a big deal I guess. If something comes up I'll let you know because that's really odd.

Thanks for the help!

Also, I'm thinking of writing a tut at some point but I doubt it'll be concise as some would wish. It's one of those apps I want to gush on about. Besides, after using blockers for 10+ years they're handy but using >10 blocklists seems excessive prefer being conservative.

Hi I have just upgrqaded to pfsense 2.3B and am having a problem with the pfBlockerNG webserver service.
The service will not start for some reason. I do get a crash report from pfsense.

I have tried reinstalling, removing the package completely and then installing.

It would be great if you could have a look at this.
BTW Thanks for a great package.

pfSense moved from lighttpd to nginx in the beta which broke pfBNG (along with all other packages relying on lighttpd). I believe the author is working on an update.

Ok Thank you.
Since the package was available for 2.3 I thought it was already done.

Hi trumee,

Some of those download fails are due to cURL errors. See the messages below. Set those to "Flex".

@trumee:

SSL: no alternative certificate subject name matches target host name 'feeds.dshield.org'
SSL certificate problem: unable to get local issuer certificate Retry in 5 seconds…

Also Dangerulez and VMX are being blocked by other Firewall Lists.

Yes the recent changes in pfense 2.3 from Lighttpd to NGINX broke the DNSBL feature… I will be submitting a PR to fix this up soon....

Its not an error… Its just a notice to say that its rebuilding the database. Possibly due to a "Force Reload" or re-enabling pfBlockerNG... or adding/removing a DNSBL Alias/Feeds...

@BBcan177, this is going to take some explaining. :) This feature affects other services, but let's just use AWS as an example.

AWS controls (among many, many others) the entire 54.240.128.0/18 range, which means that all /24 ranges from 54.240.128.0/24-54.240.191.0/24 are included. Since AWS allows others to use their servers, it's highly likely that many of those /24 ranges are going to be flagged.

Let's say that 128, 129, 140, 141, 142, 143, 144 get flagged in a particular /24. As far as AWS is concerned, there's no correlation which implies that 130, 139 or 145 are the same individual or group. This is especially true for CloudFront where the IP assignments mean nothing.

So the entire /24 net gets blacklisted when, in actuality, for these particular subnets, the relationships between IPs on the same /24 subnet is almost zero.

What I'd like would be for a way to say: "Hey, go ahead and parse out something like this: https://ip-ranges.amazonaws.com/ip-ranges.json and, if the IPs are within those ranges, still blacklist them, but don't add them to the list for reputation processing."

Thoughts?

Hi abujammy, Its best to use the Country code exclusion for Reputation and add "USA" to the list of exclusions.

Wow! BBcan177. Wow.

I've been gone for such a long time, I come back and pfBlockerNG is a hit! This is so cool. I'm so glad that you stepped up and helped move this idea. Thanks to Marcello Coutinho for helping me get pfBlocker (back when it was IP blocklist and country Block) off the ground from it's first inception back when it was release 0.1.

This is absolutely awesome. And you gave throwback credit to me and Marcello Coutinho.

Well done! This is why I love the pfsense community. We all work together to make our worlds better.

Thanks… Most don't realize all the effort that goes into developing and maintaining a package with an ever changing landscape... ;) welcome back...

Hello,
what did you prefere as blocked iplist?
did you have some web service that you know where i can buy access to some blocklist that i can insert by URL and forget it?
did you know also some of this service for Whitelist (like googlebot and similar)
tnx for your help.

Is it possible to block a list of dynamic IP's but only specific ports?

We get a lot of spam H.323 calls originating from AWS (185+ EC2 IP ranges) and DigitalOcean (10+ IP ranges) and others. We'd like to automate the blacklisting but only on port's 1503 and 1720.

Expert Mode Question: Most of the originator calls are named "unknown" or "cisco" and it would be great to parse those out and block those, though I'm betting that's beyond the scope of pfBlockerNG.

Here is link to a script to import ~50 blocklists…
https://forum.pfsense.org/index.php?topic=86212.msg549973#msg549973

I think there are some Whitelists available... But I don't have those URLs myself... Google search and/or hopefully other users can share some URLs for whitelisting...
