PfBlocker

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

Guest · Nov 9, 2011, 4:24 AM

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?

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

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

Check rules with pfBlocker enabled and disabled

Guest · Nov 9, 2011, 5:40 AM

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.

If wired and wireless machines are on the same subnet and using the same dhcp, I have no idea how pfsense or pfblocker could block one and do not block other. It's weird to me.

I have found by moving the rule after the allow rules the wireless clients work. But, that doesn't seem right does it?

Guest · Nov 9, 2011, 5:57 AM

I agree that it doesn't make sense. What happens to one should happen to the other. But, did you see what I said about moving the rule to the bottom?

No it's not.

An outbound rule blocks access from any to pfblockerAlias.

If you have one rule that permits traffic, the deny rule will have no effect.

marcelloc · Nov 9, 2011, 6:20 AM

Maybe level3 list is blocking all your network and the pfsense keep-state for your machine gives you a false diagnostics.

Remove level3 list and see if it works.

HI everybody,

Version 0.1.4.5 is out with all planned features coded. 8)

main changes:

Dashboard widget includes package hit on applied aliases (10 second update)
Change in rule description to allow widget package count
Update frequency implemented

Important note for custom rules

keep aliasname in the beggining of rule description and do not end description with 'rule'.

Once again, thank you for testing this amazing new tool for pfsense. ;)

RonpfS · Nov 11, 2011, 5:12 AM

Just reinstalled.

Strange things happens when you switch to Alias
Description: pfblockerWAN Inbound rule will disappear
Description: pfblockerWAN Inbound will persist

Still showing 0 in the widget after 10 minutes

marcelloc · Nov 11, 2011, 5:43 AM

I've changed important note for better understanding.

Aliasname something rule will be removed by package.

To test rule packet count, block your own country While you are locally on your office/home.

DO NOT TRY THIS REMOTELY.

A less risky test is:

define your own country action as alias only
create a rule that deny outbound icmp access on lan.
include description as described
apply rules
Open Dashboard
try to Ping someone on your country.

RonpfS · Nov 11, 2011, 6:01 AM

Still showing 0

I picked one host in the Diagnostics: Tables pfblocker table.
I can ping from LAN or pfsense no problem
Nothing is showed as blocked in the firewall logs !??

rules are on WAN only

Reject and log * 	* 	* 	pfBlockerWAN 	* 	* 	none 	  	pfBlockerWAN Outbound  
Block and log * 	pfBlockerWAN 	* 	* 	* 	* 	none 	  	pfBlockerWAN Inbound

marcelloc · Nov 11, 2011, 6:04 AM

If you are testing from lan, the blocking rule must be on lan.

It's a statefull firewall. All rules are set where communication begins.

RonpfS · Nov 11, 2011, 6:17 AM

So I should have

on the LAN
Reject and log * * * pfBlockerWAN * * none pfBlockerWAN LAN - Outbound
on the
WAN Block and log * pfBlockerWAN * * * * none pfBlockerWAN WAN - Inbound

I see the widget Packet number changes ;o)

How do you block the pfsense box from accessing these aliases?

marcelloc · Nov 11, 2011, 6:22 AM

On floating rules, but it may not show in widget.

Floating rules are not impelmented in this version but you can apply pfBlocker alias on it.

RonpfS · Nov 11, 2011, 6:53 AM

I just created a rule on the Floating tab…. and the Packets blocked are updated in the widget ;D

However the rule

Reject and log * * * pfBlockerWAN * * none pfBlockerWAN Floating Outbound

disappeared in the Floating tab after a save in pfBlocker …..!!!

same thing with

pfBlockerWAN Floating
pf BlockerWAN Whatever

bummer :(

marcelloc · Nov 11, 2011, 11:09 AM

As I told you, floating rules are not implemented but i'll try the same test here and see what happens.
