PfBlocker

The default way to block spam is inbound as you do not want them to send email to you.

You can also change action to alias only and create a block rule only on inbound smtp connections.

If i enable the top spammers alias included in pfblocker on outbound those hostnames you specified are not accessible.

Top spammers is just a shortcut for countries that send many spams.

The best way to block this is changing action to alias only and create an inbound rule denying smtp connections.

I chose alias only and set outbound and inbound block; I'm still getting to the sites. The one interesting thing is that before I chose the option block outbound this morning I had it set to block inbound yesterday before I went home and when I loaded the widget this morning it had some packets listed. It doesn't have anything listed right now… I may need to reboot the server; I'll try that later on today.

There is no need to reboot, all rules are applied when you save config.

try this:

select only one country
apply
got to diagnostics -> table
select alias you applied country
check if the websites ip is in any of network CIDRS listed

Just to be sure you understand how rules work.

inbound rules -> applied on source side of wan rules
outbound rules -> applied on destination side of lan rules
Floating rules -> apply rules to block pfsense to reach something

I don't know what is happening, but I just put a specific rule in place of the pfBlocker and the Indian site is still not getting blocked; could it be due to squid?
Thanks!

Finally an answer. It's squid. :)

Create the same rule on floating rules.

Squid goes to internet using localhost, so lan rules will not match any squid access.

mentalhemroids · Nov 16, 2011, 9:23 PM

Okay, so question… do I need to have both WAN and LAN selected in the floating rule? I had just one and things seemed to still go through; with both the sites were blocked. I guess it could be that it's cached on my pc here, but I am getting things blocked on another pc with just LAN selected.

Thanks for your help marcelloc!

Well, it's time for first release.

pfblocker 1.0 is out. No changes from last beta version.

tommyboy180 · Nov 17, 2011, 5:35 PM

Congratulations! Excellent work marcelloc!

mentalhemroids · Nov 17, 2011, 8:25 PM

Another question… am I supposed to see numbers in the packets column? Mine are blank... Thanks.

Numbers will appear only when you have applied rules to aliases pfBlocker creates.

Also post pfsense version and hardware used.

I have the status showing up and running ver 1.0 pfBlocker on pfSense 2.0 x86; I don't know what else to tell you.

@mentalhemroids

I guess the PfBlocker Widget counters are built by scanning the Firewall rule descriptions.

When you use pfBlocker Aliasname in Firewall rules, you have to start the description with pfBlocker Aliasname for the widget to keep track.

in your case "pfBlockerAsia bla bla lba'

however, if you description end with 'rule' it would be recognized as auto generated and removed by pfblocker on save.

@marcelloc:

I've changed important note for better understanding.

Aliasname something rule will be removed by package.

mentalhemroids · Nov 18, 2011, 4:05 AM

@RonpfS - Thanks for the tip… I would have never figured that out! I at least have 0's showing up now; I'll see if they populate with numbers.

marcelloc · Nov 18, 2011, 4:23 AM

Sorry for that. I forgot to include this info in field description.

It will be there in next release.

Hey all!

I'm currently am running pfSense RC1 2.0 and Country Block. County Block works perfectly and is very easy to use for a novice like me.

Is pfBlocker as easy to use as County Block to block IPs from specific countries? Are there any documents on-line I can read to learn how to use pfBlocker? I'm upgrading to the latest version of pfSense 2.0 next week and don't want to have any problems.

Unlike everyone else here, I'm not a programming guru. I'm learning, but I have a long way to go!

Thanks! :D

Bummer · Nov 18, 2011, 5:25 PM

Wow - I looked at the screen shots and this is easy to for anyone to use. I'm impressed.

A dumb question - are social networks like Facebook, Twitter, etc? Or is it something else?

marcelloc · Nov 18, 2011, 5:41 PM

take a look on ipblocklist website or any other that distribute lists.

If you now socialnetworks ip ranges, you have an option to include in custom list.

Hi,

installed the release totay on an Alix running nanobsd pfsense 2.0 - but get this:

Nov 18 20:55:24 	kernel: pid 32813 (php), uid 0, was killed: out of swap space
Nov 18 20:55:24 	php: : [pfblocker] pfblocker_xmlrpc_sync.php is starting.

How do I get rid of the swap issue (RAM issue probably as nanobsd shouldn't swap - but the RAM is at 35% when this happens). Power LED of Alix keeps blinking.
Only happens if this package is installed but then also if the only thing active is the TopSpammers list (deny inbound). All other disabled.

Thanks!
