How often do you update the enabled lists? I'm using pfSense for my home router/firewall with the following lists :

How often do you update the enabled lists?
Hi postduif,
In the pfblockerng.log (This can be viewed in the Log Browser), after the downloads are completed, you will see a section called :
"==[ [b]Last Updated List Summary ]=="
This will show you the last updated timestamp of the Threat Sources. You can change the lists to update once per hour and follow the log file for a few days to see the Update Frequency of each list and adjust accordingly.
I would recommend atleast a once a day for most, some are updated more frequently (1-4hrs).
Also the first step in any Cron event is to check the timestamp of the remote server and see if its the same as the previous download, then the download is skipped for that particular list. Also note the blocklist.de has several other lists available (you show only the ssh list).
I have also indicated in several posts in this thread to be more concerned about the "Outbound" traffic.
Typically for "Home" use, you most likely do not have any open ports. As pfSense is a Stateful Firewall by design, it is blocking all unsolicited traffic on the inbound WAN. But if a device on the LAN makes a request to any of these Malicious IPs, it will go thru and not protect your devices as you have not configured any "OUTBOUND" rules. If you do have open WAN ports, then you can add specific Alias Type Rules to protect those individual ports on the "Inbound" WAN.
Hope this helps!

So i just finished reading this entire 36 page thread prior to posting any questions when installing/setting up, as I definitely do not consider myself an "engineer." I wanted to thank everyone involved (not just limited to testing) and most notably BBcan177 for his time and effort contributed.

Really helps for understanding pfblockerng, thanks.
The only inbound services i'm using are ssh (on port 6622 which forwards to an internal server on port 22, but is only allowed from a specific source IP) and Openvpn on port 1194.
What's your advice, only use deny_outbound on my lists? Or deny_both? -
If you are restricting those two ports for SSH and OpenVPN to a select few IPs, then it doesn't protect you to have pfBNG "Inbound" rules as the "Implicit Deny" on the WAN is already dropping all unsolicited traffic.
If you want to see the activity "noise" that is being implicitly blocked on the WAN, you can use "Deny Both" but it will slightly impact performance. FreeBSD "pf" is quite capable to process the IPs and lookup the Alias Tables, however its not offering any protection to your network as stated above.
You will see less activity in the Widget/Alert Logs without the "Deny Inbound" rules but that is a good thing. You should really be looking at what is being blocked. So if a LAN device is showing blocked activity to a Malicious IP, you should be investigating why?
By un-neccessarily using the "Deny Both" rules, you are cluttering your alerts log and you can miss the real malicious activity that you should be looking out for.
You don't just want to turn it on, and forget about it.
If for example you have a single port (or a few ports) open on the WAN, you are better off in creating an "Alias Deny" rule(s), and creating a manual Firewall rule just for the Inbound port(s). This way it reduces un-necessary processing of the Inbound packets.

Via the private repository but it will be available soon as a pfsense package.
Be patient :)
How can I get access to this private repo?

Hi folks,
I have a question re. utilizing a pfBlockerNG alias. Specifically, this text:
When using 'Alias' rules, change (pfB_) to ( pfb_ ) in the beginning of rule description and use the 'Exact' spelling of the Alias (no trailing Whitespace) Custom 'Alias' rules with 'pfB_ xxx' description will be removed by package if using Auto Rule Creation.I am assuming that I don't have to change anything with respect to the alias created by pfBlockerNG itself, but when creating a rule that utilizes the alias must the rule description field contain only the alias name (with the lower case 'B' substituted in the pfb_ prefix) or can it include additional text after the alias name? The "in the beginning of rule description" wording implies (to me) that other text can follow …but the "no trailing Whitespace" implies no other text should follow. I currently have additional text in the rule description field, and the dashboard widget shows green for the alias, but I just want to be sure.
Thanks (and awesome package by the way!) ...

Hi Slab,
The Green arrow indicator, will show that there is a Rule associated with the pfBlockerNG Alias. If you add extra text to the Manual Rule Description, the Packet Count for this Manual Alias Rule in the widget might not work.

Hi, I updated from pfsense 2.2 to 2.2.1 and my pfBlockerng config got wiped. The package was uninstalled and reinstalled according to the logs
all I had was 1 alias of 1 country, type native
any ideas before I update the other 13 firewalls?
Thank you for your time

Hi Seqteq,
There is a checkbox in the General Tab called "Keep Settings" that needs to be enabled. On all new installations it has been defaulted to "On".
Its strange that your posted log has "pfBlocker" when it should be "pfBlockerNG"

pfBlocker package does not exist any more. No configuration from there will be carried over to pfBlockerNG. Restart from scratch.

Ah, thanks I'll check that tomorrow.
Just noticed the ng was missing in the log. I was definitely using ng in 2.2 and ng is definitely what got installed after the 2.2.1 update. iDunno. I adopted 2.2 for this appliance early, before the ng release, but that got replaced like the day after ng dropped. -
There's no way the package would reinstall in 1 second. Probably you have too many boxes to keep track of what actually was there.

Hello
Got Something strange with PpBlockerNG on alerts tab
Fatal error: Call to undefined function subnetv6_expand() in /etc/inc/util.inc on line 714
Any idea what is going wrong ?
Thanks

pfBlockerNG v1.06 has been Merged by the Devs.
Changelog:
-
Previously when deleting all IPs in the pfBlockerNGSuppress Alias, it would not
clear the widget Suppression Counter. This version fixes that issue as reported by user "Panz". -
Merged recent changes in pfSense diag_dns.php into pfblockerng_diag_dns.php to keep code base current.
-
Change Release to "Stable" from previous "Beta" Status.
Notes -
The issue reported by "stanthewizard" above is partially due to a missing function in pfSense (subnetv6_expand). I expect that I will need to submit a new Pull Request to fix this issue. I provided him a workaround to fix his issue for now.

And I thank you for that again

Hi, Thanks for a great pkg.
I'm having problem with port forwards and UPnP & NAT-PMP.
I use this settings for pfBlockerNG:
Marked all lists
Top 20 and Asia is blocked, both rest blocked inbound.
I have added custom lists from Bluetack ads/proxy/spyware and from Squidblacklist ads. All deny both
Set rule order pfSense pass/match | pfB_pass/match | pfB_block/rejectTIA

You need to describe what is your problem…
I use this settings for pfBlockerNG:

Top 20 and Asia is blocked, both rest blocked inbound.What all lists? The country lists? So you blocked whole world inbound, or what? I don't understand your description at all. Plus, block is default on WAN. Are you actually running any service locally that you need to limit access to?
