PfBlocker
-
Hello, I've recently installed pfblocker and been trying it out. Unfortunately I'm getting this error.
This is just an FYI.There were error(s) loading the rules: /tmp/rules.debug:25: cannot define table pfBlockerTopSpammers: Cannot allocate memory - The line in question reads [25]: table <pfblockertopspammers>persist file "/var/db/aliastables/pfBlockerTopSpammers.txt"
some details;
pfsense version: 2.1-RC0 (i386) built on Fri Jun 14 16:39:04 EDT 2013machine has 4gb of ram, swap space is 2gb, roughly 2gb free.
Memory useage displays as 7% on dashboard.pfBlocker was configured to deny in/out on wan/lan, all countries selected in topSpammers list.</pfblockertopspammers>
Did you go to system > advanced > firewall tab and increase Firewall Maximum Table Entries? if not increase that. Generally have to increase it quite a bit depending on all the lists you load. Mine is set to 999999999

OK one question - not seen it here so has anyone else noticed that on restart pfBlocker re-organises the rules and sticks its rules back at the top? Since I have two WAN's (WAN and OPT1) I also prefer the rules to live in 'floating' so they get applied to both interfaces and I only need to manage in one - but pFBlocker keeps putting them back into WAN and OPT1 I realise that they won't get 'executed' if they are found in floating first but it makes my configuration untidy and I do have a degree of OCD about such things.
I have a need for certain machines to come BEFORE the ad blocking - (I use the subscribed ADBlock list from iblocklist.com) but it blocks many 'robots' too, since the web server isn't used for browsing I placed it before the ad blocker rule - but on firewall restart I need to move things around again.
This just me or has anyone else spotted it?

Considering it's documented behaviour… huh.
-
Well it may be I confess to not reading it all, just enough to get configured and running, don't have hours to burn trawling through pages and pages of small print.
So documented it may be but it is a feature that I could do without - rules should stay where I put them since rules are executed in the order presented and I (or any other) user should be able to set the execution preference and expect it to be obeyed.

Rules will stay where you want once you've read the documentation and created the lists as "Alias only" in "List Action" and placed them wherever you want.
-
they are configured as alias only and yet I've had to re-arrange them 3 times now. I did the aliasing bit specifically to make sure that certain 'targets' were exempt from certain rulesets.
I have a Spammer set, a malicious set and an advertising set Spammer and Malicious I put into floating because I want them to impact on all, I then have the web server followed by the advertising set … the server is aliased as is the local subnet, since the server is encountered first i.e. before the ads then robots etc still work - anything else gets advertising blocked.
I'll scan the documentation again but I'm sure I did it right.
-
My lists are aliased - Spammer1, Malicious1 and ads1, which translate to pfblockerMalicious1, pfblockerSpammer1 and pfblockerAds1 in the rules lists, these carry a comment 'do not edit this alias'
-
Well maybe it's fixed - appreciate the input, I hadn't spotted the 'alias only' in the dropdown box of the pfBlocker itself, I had seen the 'rules and alias only' but since everything I do uses aliases figured that was it - wrong.
I rebooted and things stayed put so despite the sarcasm re documentation I do appreciate the input ;)

I just started having a possible issue with pfblocker. Even though I have it enabled and all the aliases are created and the CIDRs are present on the dashboard widget, the dashboard widget also shows red arrows pointing down in the status column. What does that mean? I could have sworn the column had green arrows pointing up. ???

Did you create any rules on WAN?
-
No I didn't. The only rules are the rules that block private and bogon networks.

Well, that is the problem… Create something safe there (like, access from 127.0.0.1 to some port). Known bug.
-
That fixed it! I created a safe rule on the WAN interface and even disabled it. Perhaps a "dummy" rule could be created as an option for those of us who run a stripped down firewall like I'm using.
Thanks, doktornotor! :)
-
Well it'd be better to fix the bug instead of creating the dummy rules… lol :D
-
You got that right!
-
When you enable the countries, it should automatically put a rule up if you tell it to block inbound/outbound.. No need to manually create a rule. All of mine auto generated..

Let me restate the problem: if your WAN contains no rules (beyond the default pseudo-rules - block private/bogon networks) this does NOT work. The rules are not added and the enable pfBlocker checkbox gets unchecked, and the widget looks as shown in this post. BUG.

Loading package instructions...I just updated to 2.1 release on my box here. Getting stuck at this while trying to reload pfblocker. Help!
Thanks! :)

Anyone else running pfblocker that's updated to 2.1 had issues with lists not updating / populating - all my list URL's are valid, reduced update time to 1 hour but the IP's aren't getting read / or the aliases populated.
As a result the alias is not 'created' and raises rule alerts for unreachable alias's.
Tried uninstalling and re-installing it didn't help - deleted the lists and re-added and that didn't help either …
Also getting a notice that Wan gateway is unknown not using it - which is utter tosh because it is both present and connected - this may or may not be related to pfBlocker
UPDATE : Typing the above prompted a grey cell - I went to check my 'routing' tables and when 2.1 was installed (2.0.3 update) the interfaces got renamed but the routing gateways did not - OPT1 did to OPT1_PPPOE but not WAN which in the system was now WAN_PPPOE ... only in the routing table it wasn't it was still 'WAN' ...
Sorting this sorted pfBlocker ...
