PfBlocker

johnodon

You could make a list with alias only and then just add the firewall rule on both wan and lan to permit it. That way you only have one list but reference it in both locations for both ways.

Good idea! :)

Thanks!

To use this way, you may need to change pfblocker action to alias only and then create your rules.

By default, pfblocker stays on top of rules.

This only happens if I reboot/shutdown my pfSense, when I perform boot it's there (this is why is important to perform at last a reboot to check if everything comes up fine again).

I didn't changed any of those files, I'm only blocking that area from the files it came with pfBlocker.

Any solution?

Did you go to system > Advanced > Firewall/Nat tab and increase the Firewall Maximum Table Entries?

I have had to increase mine quite a bit to run all my tables. I currently have mine set to 999999999 and no longer get any memory allocation errors.

Nope.

Will do. Hope is only this.

I've been really busy (figuring out Postfix).
I don't have time to update my previously posted spam lists.

(Note: http://forum.pfsense.org/index.php/topic,42543.msg258273.html#msg258273)

For now I have a routine that extracts all new Spam IPs into one list - updated 2x/hour.
http://dl.dropbox.com/u/71477228/freshspam1.txt

I'm also now harvesting spam IPs from a 2nd email server I manage.
http://dl.dropbox.com/u/71477228/freshspam2.txt

As I update these routines, the next rewrites will:

filter out any IPs of major WebMail providers (GMail, AOL, Yahoo, Hotmail, etc)

For now, I whitelist US Yahoo email servers and Hotmail/Live/Microsoft Hosting.
http://dl.dropbox.com/u/71477228/YahooIPsUS.txt
http://dl.dropbox.com/u/71477228/hotmail.comIPs.txt

Sort spam IPs into my existing US and non-US spam lists
Include relevant comment for each IP
Drop off addresses that haven't had a spam hit in x#of days.

Edit: Here's a list of AOL outbound Email Servers
http://dl.dropbox.com/u/71477228/AOL_MailIPs.txt

It's compiled from the information on this page.

These spam lists have been effective w/o giving me false positives.

This is a list of fresh US Spam IPs from a major source, updated hourly.
http://dl.dropbox.com/u/71477228/usspamips.txt

This list contains fresh Spam IPs from US and other countries, updated hourly.
I'll eventually get it sorted into US/non-US.
http://dl.dropbox.com/u/71477228/worldspamips.txt

PM me if you want more detail about them.

Just an FYI.

I looked around a lot for a versatile, online IP converter.
The only one I ever found is by Bluetack and it never showed up in any of my Google search queries.

Hi there,

Sorry if I'm being a bit thick here and/or this question has already been asked, but can i use this package download blocklists, create Aliases against them, and then use standard pfsense firewall rules to block those ranges talking to/from just ONE port on a particular IP address (ie, allow it for all other ports)?

Thanks!

marcelloc

S_D,

Sure you can, just configure pfblocker and set action to alias only.

This way pfblocker download,create the lists and you can assgin these aliases to your own rules.

Marcello Coutinho

Perfect! Thanks for the reply. I'll set it up tonight.

Hi :)

issue with system being stuck at "configuring firewall…" after reboot/startup with WAN interface down(or having wrong IP config)
using ctrl-c at console doesn't help.

i think the issue is pf tries to grab the lists but keeps waiting?

I tried uninstalling pfblocker and it worked fine with WAN down.
removed aliases + used deny inbound did not help

I'm using pfblocker 1.0.2 and pfs nanobsd 2.0.1

Thank u!

marcelloc

I've pushed an update to avoid downloads during boot process, reinstall the package and test again.

Try to get some info on system logs.

Pfsense is trying to update urltables applied by pfblocker during boot.

I'll try to find a way to prevent this if there is no link/ip/webserver up.

I got the dreaded error trying to load the Level 1 list:

There were error(s) loading the rules: /tmp/rules.debug:16: cannot define table pfBlockerLevel1:
 Cannot allocate memory pfctl: Syntax error in config file: pf rules not loaded - The line in question reads
 [16]: table <pfblockerlevel1> persist file "/var/db/aliastables/pfBlockerLevel1.txt"</pfblockerlevel1>

My Firewall Maximum Table Entries is set to 4294967295 and still no love. Freshly installed pfSense and pfBlocker, most everything at defaults. Just the one block list. 512MB of RAM, only 32% in use. 1GHZ CPU.

Does anyone have any suggestions?

Thanks.

TrickyWidget

I got this suggestion from marcelloc:

@marcelloc:

Unselect the list, apply pfblocker config.

change again table max entries and apply config.

when you are sure that the new config is applied, try to enable again the list.

That seemed to work for a while, but the error eventually returned (or at once on reboot).

I've got a RAM upgrade on the way to see if going to 1GB helps any.

Hi,

On my physical 2.0.1 box pfblocker is making duplicate WAN rules. I only though to check after reading this thread: http://forum.pfsense.org/index.php/topic,50408.0.html . I tried to remove + reinstall the package, but it saved the config files and still keeps making duplicates.

pfblocker works fine on my VM, which also has floating rules though I've only used the latest version on it.

Is there a file / config I should also remove addition to the pfblocker package to make sure nothing is carried on.

Regards,
Joona
