PfBlocker
-
Semi-fix, I added the prefix "pfBlockerBadList1" and "pfBlockerBadList2" to the beginning of the respecive WAN rule for each and now both "pfBlockerBadList1" and "pfBlockerBadList2" show up in the widget and are recognized as being up; while this does not solve the original widget problem it does let me know at a glance that my lists are functioning; and as a nice additional benefit the packets that are blocked by the respective individual nested aliases within the two lists are still recorded correctly under the original widget list names. Sweet! :D
Here is a pictorial example of the lists:
(The blocked packets are not showing now beacause I restarted, but will show up under the individual list names, not BadList1/2, I like this.)

All issues we found has already been fixed.
The last thing to code is lists update frequency.
can you add the option to update weekly? it only allows up to daily right now ..which is awesome.. but sometimes iblocklist.com denies updating that frequently. at least it does on peerblock 1.2+ …
???

Isn't this done in a cron job? I think you can just set the cron job wday from a number 0-6 to set the day (somebody correct me if I am wrong).

The pfBlocker frequency is set in the pfBlocker GUI per each individual Blocklist. (Never, 1hour, 4hour, or 24hours)
The Cron job that you see is to Update the URL tables which in most cases shouldn't be played with.

Is there a way that we can see what IP's are being currently blocked by PFblocker? The widget shows 85 blocked for a given list, I would like to know which one from that list are being blocked?
Thanks
-
To see what IP's were blocked by pfBlocker, you need to look at the Firewall log.
The widget only displays the total number of ips per blocklist.
-
I'm also having a problem "finding" the IP's that the widget is blocking. I go Status: System logs: Firewall but I see a bunch of traffic blocked. I added some allow rules in pfblocker and I see some IP's allowed but don't know what list they are from or any way to tell they are from pfblocker.
I grepped my syslogs and do not see anything except for stuff like this: /pkg_edit.php: [pfblocker] pfblocker_xmlrpc_sync.php is starting. I can see the see the pfblocker lists in the widget on the dashboard counting packets and I can see the IP lists in the Diagnostics: Tables so I know it's working, but I'm not sure where to be looking for detailed info such as logs that say pfblocker and then the list name and the IP's that were blocked. Any info will help
-
For the blocklists that you created in pfBlocker, did you use "aliases"? This is the preferred way to utilize pfBlocker.
Once the aliases are created by the pfBlocker program, you can add block or reject rules on each interface utilizing the defined aliases.
-
Thanks I did not realize that alias_only was the proper way to implement this.I was originally using the deny drop down. I've modified the lists to use alias_only and added the rules on the interfaces. I'm still unclear as to how to know that pfBlocker was the reason an IP was blocked (or more specifically which alias I would need to check).
Is there a log entry that's created that say something like "pfBlocker [alias name]: log entry"and the alias name or something in the log?
Also is it normal to have the pfBlocker widget show the lists and the "up" status but the packets field is blank? Sorry if I'm missing something obvious.
-
When you create a block or reject rule for an alias, any ip addresses that are listed in a particular alias will shows blocks/rejects in the firewall log.
I like to have separate aliases so i can tell which list/alias is blocking/rejecting.
The widget will show a green up arrow once a rule is associated to an alias name. The packet counter has never worked from what I can tell.
When you look at the firewall logs it will show the block/reject by interface, Rule name, ip address etc..
If you modify a rule, it can mismatch the alerts to the firewall logs. This hopefully will be fixed in the next release (2.2). So before making changes to rules it's a good habit to look at the firewall logs first.
-
I understand the block/reject rules based on an alias. That part is working as expected for the most part and there are now sites that I can't ping. In my logs I do not see any reference to pfBlocker or which alias the IP's belong to. You stated that you have separate aliases (and I do too) but I'm wondering if there is another step I'm missing.
Basically, this isn't the case for me but this is what I'm after:
When you look at the firewall logs it will show the block/reject by interface, Rule name, ip address etc..
All I get is "rule <number>(match): block in <interface>: and then some protocol stuff, ttl, id, offset, and flags. Maybe something needs to be cleared or reset?</interface></number>
-
When you add the rules, make sure you click "log packets that are handled by this rule" so that they show up in the Firewall logs
-
Under Firewall: pfBlocker, I have the "Enable Logging" checked. Also for each pfBlocker alias (one firewall rule per alias) I also have "Log packets that are handled by this rule" checked. I had that enabled logging checked for almost every single rule previously. Would someone be able to give me a string to grep for to see if I have any reference to that in my logs? I grepped for pfBlocker (with -i) and nothing except status messages come up. That's why I wonder if I needed to reset or reconfigure something to get it to work as expected.
-
That's odd.. did you check the firewall settings tab settings? If you don't see any alerts from pfblocker in the firewall log than greping from a shell won't get you anywhere.
When you hover over a rule that holds a pfblocker alias, does it show a list of ip addresses? Or check to see if in the Tables menu that the aliases have addresses?
If you have a block or reject rule on the LAN interface for a pfBlocker list, try to ping one of those addresses and see if it generates an alert in the firewall tab.
Maybe a reinstall of pfBlocker or start a new thread for this issue?
EDIT - if you want to grep the logs, grep for "block in on". If they alerts were there, they would also have the pfBlocker alias name (rule name)
grep -i "block in on" /var/log/*
-
Yes, the alias do have a list of IPs (with the exception of 2 lists that were massive). I've removed the 2 lists that were acting up and confirmed both in the tables menu and by hovering over the aliases. I do have the LAN rules and while I cannot ping the IP's, no logs are generated from it. I have reinstalled pfBlocker before I started this thread but I'm going to wipe the settings and remove pfBlocker and then start fresh. I figured something isn't working properly since it seems everything is in order. Thanks for the pointers though.
-
If the blacklists are large, it can take a little longer to view the list as you hover over the rule. They are most likely working correctly.

I'm using pfblocker with a simple configuration and it might be the culprit for some wierd behavior i get in my network…
Configuration:
Inbound Interfaces: WAN
Inbound deny action: BlockOutbound Interfaces: LAN
Outbound deny action: RejectEvery list & country blocked is with "deny inbound".
Is the setting for the outbound interfaces needed if all the actual lists and countries are deny inbound only?...
i suspect pfblocked is blocking some valid outgoing traffic for a specific lan service (some outgoing sendmail) but i cant find anything in the logs.
This behavior only gets fixed after i restart the whole firewall, and works fine for about 10-15 days.After that, no outgoing mails are possible, till i restart the machine. Everything else seems to be working fine, only connections to the specific mail relay server.
Please give me some insight on what i should be looking for to fix the problem permanently.

The Country Codes is not being supported any longer and should not be used as it is Out of Date this functionality should be removed from the package. Hopefully pfBlocker will be getting a face lift in pfSense v 2.2.?

Hello,
So I just installed pfBlocker and I am trying to find some good ad blocking lists. My comparison list(s) are from AdAway on Android which pulls from the below sites.
http://hosts-file.net/.%5Cad_servers.txt
http://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts$showintro=0&mimetype=plaintext
http://winhelp2002.mvps.org/hosts.txtThe test site I am using to check the ad blocking is http://extreme.outervision.com/psucalculatorlite.jsp
When using AdAway on Android I don't get any ads along the sides/top of the above site. I tried using the Bluetrack ad list from here http://list.iblocklist.com/?list=dgxtneitpuvgqqcpfulq&fileformat=p2p&archiveformat=gz but I still get ads on the site.
Can pfblocker use a list of URLs or does it only do IP address? If it only does IP address I guess that is fine, I have made a bash script that will pull the lists from the AdAway sites and convert the URLs into IP address. My only issue with the script I have is I don't know of a way to convert all of the IP addresses into a smaller list of CDIR networks so I have just made each IP into its own network by adding a /32 which I am sure is an awful idea. So if anyone knows how to convert a huge amount of IP addresses into CDIR notation or if there is a way to use URLs with pfblocker can you please let me know. Thanks.

Hi w1ll1am,
These lists are all URL and can't be used by pfBlocker.
pfBlocker only accepts the following formats:
Note:
Compressed lists must be in gz format.
Downloaded or local file must have only one network per line and could follows PeerBlock syntax or this below:
Network ranges: 172.16.1.0-172.16.1.255
IP Address: 172.16.1.10
CIDR: 172.16.1.0/24pfBlocker already can accept the IBlock lists without any conversion (as they are in a range format already), but the following will also convert the file which you could link pfBlocker to a local txt file.
The following will download and convert that file to a range acceptable by pfBlocker.
fetch -v -o infile.gz -T 20 ?list=dgxtneitpuvgqqcpfulq&fileformat=p2p&archiveformat=gz
gunzip infile.gzcat infile | cut -d':' -f2
I posted several lists here:
