Make sure you created the Alias URL Tables correctly. Cino posted his setup here
https://forum.pfsense.org/index.php?topic=78062.msg427132#msg427132
-
yeah, there's where I copied the setup from, its been a long day so its completely possible Ive screwed something up but it seems basic enough (isn't this where all errors are made, the easy stuff!?)
each rule looks like this….
Edit: Hang on: it says use small IP lists under 3000 there….
and the alias page looks like this.....(not sure why mine shows a section of the data under each rule mind.....version difference with 2.1.4?)
-
We all make mistakes and I think the issue is that you created a "URL" Alias instead of a "URL Table" Alias.
When its a URL, it has a max amount of IPs that it can hold.
You should also keep the Description the same as the Alias Name, so its easier to see in the Logs and Rules GUI.
Easy Fix… ;)
-
you are right…..knew it would be a newb mistake :-[
thanks for your help this evening....and again, thanks for all the work you've put into this. -
My pleasure! Keep those Bastards out of your Network…. 8)

Sorry….me again :)
I've just ploughed through configuring Suricata and have a few issues in the log I was curious about understanding, are these anything I should worry about or just disable these rules?
FYI: I'm running this with jflsakfja's suggested list and the ETFree list (want to try this out before coughing up some serious coin (compared to VRT home licence) for the ETPro list.<snip>2/7/2014 -- 18:16:11 - <error>-- [ERRCODE: SC_ERR_WITHIN_INVALID(106)] - within argument "-4" is less than the content length "4" which is invalid, since this will never match.

I Have updated the pf IP Reputation Manager Script to version 2.3.3
You can review the revisions in my GIST.
https://gist.github.com/BBcan17/67e8c456cb399fbe02ee
For pfiprep make the changes to your existing file or just overwrite and add your changes as required.
For pfiprepman, just backup the previous 2.3.2 version and replace with the latest 2.3.3 version.
CHANGELOG
***** Added Support to use the Emerging Threats IQRISK IP Reputation Lists
(Requires Subscription)
***** Some more of the Lists now support HTTPS downloads, and the collect lines
have been updated.
***** Added a [ [b]./pfiprep killdb dskip ] function which will reset the database with
the existing Downloaded Files
***** Moved Blocklist.de Blocklist from the Mail Server Section to the Regular
Section, as this list has more than Mail Server Blocklists. Refer to INFO URL in the
script.
***** Added a few other Blocklists
***** Script can now process IBlock Subscription Lists
***** Script can now process SquidBlock lists that are IP based.
***** Added "plog=yes" option to Log Errors to the pfSense System LogI recommend running
[ [b] ./pfiprep killdb ] with version changes or [ [b]./pfiprep killdb dskip ]
If you find any Bugs please let me know and I will promptly fix them.
Feedback is always Welcome!

I have Updated the pfIP_Reputation.widget.php file:
1. It now displays the Last Update (Date/Time) per Alias Table.
2. Displays a Total Blocklist Count
3. Displays "All Downloads Successful" or it will List any "FAILED" Downloads.
The updated file can be found in my Gist @
https://gist.github.com/BBcan17/67e8c456cb399fbe02ee#file-pfip_reputation-widget-phpThe file will need to be saved in the
/usr/local/www/widgets/widgets folder [ [b]pfIP_Reputation.widget.php ]
Lines 36 and 37 need to be edited to the "Masterfile" and the "Daily.log" file locations.
From the Status:Dashboard, click on the "+" Icon to add the widget.
See attached for a screenshot of what the Updated Widget Looks like:
Previous pfIP_Rep widget at Top
New - Widget showing (All Downloads Successful)
New - Widget Showing a Failed DownloadWith these changes, you can effectively manage the pfIP_Reputation Manager without needing to use the Shell to see its status. If You have any other suggestions to improve the widget, please let me know.

nice :)

Working. Sadly the no packets counted bug is back for me.
Existing install without importing back-up xml files. Just added the new aliases and rules as usual. Normally importing back-up firewall rules breaks it..Checking log file works, update status also. Just no packets :p (yes yes, quick option, logging option, the whole shambles - rules are working fine, DNS lookup also, just no packets counted on dashboard widget)
-
The rules that are using the Aliases (IR_PRI1, IR_SEC1, etc), does the Description start with the same name of the Alias? This is how the widget can match the rule to grab the hit count.
Look at my post https://forum.pfsense.org/index.php?topic=78062.msg427132#msg427132 and take a look at how I labeled the Description field.
-
just adding that it worked for me too after following Cino's method.

Thanks Cino, we must be on the same wavelength. I just sent Foetus a PM with the exact same thing! ;D
I have to take a look at that regex for the Description matching part. But for now, keep the Rule Description the same as the Alias Name.
-
And idd. Naming the rules anything else breaks it. :-X
Oh well, now that we know that.. :) -

Oh well, now that we know that.. :)The first word in it has to match the alias… after that, you can add whatever you want.

@jflsakfja:
Next up Floating tab:
Set up a rule but make these changes:| Action | Block |
| Quick | TICKED!!! |
| Interface | Hold CTRL and click on all interfaces EXCEPT LAN(admin) and SYNC |
| Direction | any |
| Source | any |
| Destination | any |I've read your post 3 times and I'm having a difficult time understanding the floating rule. The default nature of the firewall is to block incoming traffic unless you add a pass rule. As I understand it, floating rules are evaluated first. So wouldn't this rule always block incoming packets on the interface regardless of the interface rules?
-
Aside from extremely enjoying your funny writing style ( ;D ) I also think you can't get too much karma for all that you are doing with regards to helping people set up Suricata (and before that: Snort).
Thank you, secret man :P

The giant red warning under that rule should explain it. It's a rule that will ONLY apply to traffic destined for pfsense's ports. By default pfsense could open up the webgui to an undesired interface, which will not be covered by the default rule. Depending on how far away you sit from the fan, it leads to varying amounts of brown stuff raining down when "it" hits the fan. ;)
@Hollander: Finished today analyzing logs for 3,997,696 IP addresses. Those (almost) 4mil IPs were what tripped up our security systems in the first 6 months of this year. Needless to say they gained a magical place in my "Permanently Banned" Hall of Shame.
If pfsense/suricata/other logs can help identify 4mil malicious IPs, then sure as hell they deserve all the support we can give them.
@all: List has had a couple of updates don't forget to check it regularly. I'm trying to add descriptions when I edit the list, so it's obvious what I added/removed/changed, without needing to go through the entire list.
