PfBlocker

All of my rules are set to "Deny Inbound"

Hi there. I'm running into a problem syncing my two pfSense 2.0.1 systems. The aliases do not appear to be synced when I make a change within pfBlocker. If I add an alias by hand, that syncs fine. Here is the error being reported in the log of the slave system when I try to turn on the TopSpammers rule:

php: : The command '/usr/bin/grep -v '^#' '/var/db/aliastables/pfBlockerTopSpammers.txt.tmp' > '/var/db/aliastables/pfBlockerTopSpammers.txt'' returned exit code '1', the output was ''

Any hints or thoughts?

Thanks!

biogoon,

I'll try to simulate it this weekend.

I have no duplicates here, can you send screenshots of your configuration as well system version?

I think I may have found a small bug with the package… I haven't re-read all 22 pages but did some searching within the topic and couldn't find it.

I'm using squid to improve web performance and for logging.. I have setup a couple of list within pfBlocker to block inbound(WAN) and outbound(LAN) Since squid uses localhost, i figured it would need to be a floating rule for it to catch. After reading a few post, but hunch was right..

After creating the floating rules, they seem to work.. But anytime I make a change within the pfBlocker config pages or just re-save, it deleted the floating rules. I'm thinking this is because pfBlocker deletes and re-creates the Alias's when the configuration its save..

I tried to create a new alias and nest the pfBlockers alias's into it but pfSense didn't like that.. I thought about creating brand new url table alias but then that would be a waste of memory.

any thoughts?

What description did you configured on floating rule?

If it was pfBlockeraliasname something rule, then pfBlocker will remove it.

Try 'pfBlockeraliasname for squid' and see if it survive an apply

I tried that and it didn't work, but "pfBlocker-aliasname for Squid" does.. The '-' made the difference.. As always, thank you!!

Can you please explain. Does this mean if one is using Squid and pfBlocker. A floating rule for Squid is need in order for Squid to use the lists used in pfBlocker?

Yes, read this topic.

Thanks, just read it but do not fully understand. Maybe once I add the floating rule(s), I will.

marcelloc

pfSense is a statefull firewall, so all rules are applied where connections begin.

Squid does not use LAN or WAN rules but localhost rules as it starts communications to web servers locally.

The only way to apply rules on localhost, is using floating rules.

This way squid wil not be able to connect to any China web site if firewall is blocking access to China's ips.

taryezveb

Thanks for that explanation, I understand it better :) But I'm still not sure how the floating rule(s) show be properly created.

Like this?:

Action: Reject
Interface: WAN
Direction: any
Protocol: any
Source: any
Destination: pfBlockerAliasname
Description: pfBlockerAliasname-Squid

Sorry if these are obvious questions.

marcelloc

Change interface to any and direction to out.

Ok, Thanks a lot for your help! :)

Hi,

On my french install system pfBlocker never and any rules to firewall any tips? to track this down?
pfSense 2.0.1 and pfBlock 1.0.1

Thanks.

You need at least one firewall rule on interface you want to configure pfBlocker.

fsavoir

Hi,

Thanks for your reply… I did have the default rules...... Isn't enough ?
"

RFC 1918 networks * * * * * Block private networks
Reserved/not assigned by IANA * * * * * * Block bogon networks
"

Thanks.

Fred

marcelloc

Default rules are not saved on interface rules config XML.

Create a rule and then apply pfBlocker config.

Thanks again for your reply,

Could we be more specific? I need to add a rule in Firewall -> Rules then Lan or Wan ?

Such a dummy rules?

Thanks again.

Fred

Lan has a default rule, you will see pfBlocker rules there if you apply deny outbound action on your lists.

If you have no wan rules, you do not need deny inbound action on pfblocker lists as you are already blocking everything.
