PfBlocker

hubsd

thanks !

just installed pfsense and this tonight…. getting emails of this:

There were error(s) loading the rules: /tmp/rules.debug:17: cannot define table pfBlockerAfrica: Cannot allocate memory
/tmp/rules.debug:19: cannot define table pfBlockerAsia: Cannot allocate memory
/tmp/rules.debug:21: cannot define table pfBlockerEurope: Cannot allocate memory

/tmp/rules.debug:31: cannot define table pfBlockerBlockedLists: Cannot allocate memory
pfctl: Syntax error in config file: pf rules not loaded The line in question reads [17]: table <pfblockerafrica>persist file "/var/db/aliastables/pfBlockerAfrica.txt"

:( how do I fix?

edit just figured out how to up my tables size. Upped it to 100mil.

I'm testing the ad blocking lists and they aren't blocking anything. All I've done was add the lists and tell it to deny_inbound. Is there anything else I should be doing to make this work? Thanks.

Also if anyone knows of any great ad lists to help me block all the advertisements I possibly can please do let me know! :)</pfblockerafrica>

While blocking adwares, proxies, spywares the default way is outbound

Take a look in ipblocklist, the are many lists there.

Also pay attention on direction.
If you want to do not access somewhere, the action is deny outbound.
If you want that someone in somewhere do not access your network, the action is deny inbound.

If 100mil means you Speaker portuguese, there is also a pfBlocker topic in portuguese forum.

I'm American. Thanks for the clarification. I was up till 3am last night playing with this, tweaking and fixing several small issues. Still got a few left, but so far I am amazed at pfsense. This is way better than Mikrotik for my needs and its FREE. :)

Yea the quality of this package is outstanding, if i had money, i would donate to it. :D honest.

One feature request would be send all blocks to a new tab in the system logs status page called pfblocker and then have the ability to quickly add blocked ips to whitelist. Also a blocked log widget similar to the firewall logs one also.

Thanks for that, our main goal is write package that improves pfSense quality and help daily admins tasks.

I can't be done until pfsense has a way to choose log direction or prefix.

pfblocker just help alias and rule creation.When you check enable log, it include rules with log enabled.

OK that makes sense. I guess adding a easyrule rule: pass from firewall will do the same thing.

I do not have xmlrpc sync enabled but i am getting this in syslog after update list jobs.

it's just a print before if

not a big deal.

never mind If you do not have checked sync option.

My alias keeps getting knocked up to the top of the rule sets I have for my networks (I have a LAN and WLAN network). It's been happening erratically. I'm not sure what is causing it or what to do about it.

My pfBlocker rule won't stay in the order that I have here. It moves to the top and ends up blocking a lot of traffic my rules allow.[/move]

If you need custom rules before pfBocker, you must change pfBlocker action to alias only and then create your own block rules.

A shortcut to this is changing pfBlocker applied rules description before changing action.

Quinn1981

Makes sense. :)

Hey guys I'm new here and to pfsense. I noticed that when I enable pfblocker my wireless clients can longer connect to the internet but my wired. Any ideas. I'm using a linksys wireless router with dd-wrt loaded on it. It has worked forever until I enable pfblocker without any rules created. I'm a complete noob to linux/unix. Thanks in advance!!!

marcelloc

PfBlocker does not remove or include any rule different from its own rules.
Try disabling it and see what happens.

Also try to include some lists and see how it include aliases and rules.

RonpfS

You might add something about the rule being under pfBlocker control in the rules description.

marcelloc

Don't you think pfBlocker Inbound/outbound rule description is less robotic? :)

I created an outbound rule using the ads, spyware, and level 3 list. Once I enabled pfblocker all wireless client stopped accessing the internet. My wired desktop worked perfectly fine. I disabled pfblocker and the wireless clients started working again. Any ideas?

RonpfS

i know …. but the warning about the alias is very robotic :D DO NOT EDIT THIS ALIAS

but I did modify one of them and got surprised when the modification was lost :o after a pfBlocker restart.

I'm not sure now, but maybe copy or the rule disappeared too !?

In the end it is easier to just use aliases, that way you can choose the order of the rules.

When you copy a rule, you must change pfblocker description to something without pfblocker and rule

yes, it's realy usefull.

Do your wireless clients are on the same subnet as LAN users?

Check rules with pfBlocker enabled and disabled

Yeah, they are are the same subnet. The pfsense box hands out dhcp to them. The outbound rule I created comes before the default LAN rule LAN NET. Also, the ntp server in pfsense provides service to the wireless ap.
