PfBlocker

AhnHEL

Increase Firewall Maximum Table Entries under System: Advanced: Firewall and NAT
you may have to increase Firewall Maximum States at some point

I'm already up to 2 million entries, even increasing to 200 million doesnt resolve issue. Been using pfBlocker since it was first introduced and havent had an issue until now.

Edit:

Using the Top Spammers works fine, it has something to do with the iBlocks lists. Using the same bunch of lists that I PM'd you back during this post.

I ran into that kind of issue when I played with the Level 1 at some point. I was using alias only.
It looked like the table were locked by Firewall Rules, when I disabled pfblocker, the table would still showed up.
I removed pfBlocker and the table were still there under Diagnostics: Tables!!!
I install pfblocker and at some point I recovered. But I am not using Level 1 at this time.

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 10499768 bytes) in /usr/local/pkg/pfblocker.inc on line 281

It looks like very large lists.

Try to remove some lists and enable pfBlocker.

@onhel:

Getting this error now trying to enable pfBlocker, and the widget still looks like the pic i posted above.

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 10499768 bytes) in /usr/local/pkg/pfblocker.inc on line 281

do you have 128GB harddisk? meaning 134217728 bytes divided with 1024 twice is exactly 128GB

marcelloc

No, its 128mb RAM limit for php set on pfsense.

Sorry yes it was MB, not GB's.. assumed still that was kB's. :-[ :-[

I tried getting pfblocker to start, doesn't appear to be running in any of my system logs or processes. Tried reinstalling over and over, and the CIRDs in the dashboard widget still show a red down arrow. Any ideas how I can start the process manually via the shell?

marcelloc

What action did you choose for it?

You need at least one rule on interface to get pfBlocker working.

check firewall -> rules

Ah that was the reason! Didn't know that, thanks!

Good work guys! Nice new tools, usability and not to mention it works perfectly :P…..thanks for bringing two of my fav PF tools together.....Love it!

btw if anyone is using PF 2.0 as a "bridged router" ...set both options to "lan" .... just something i found out the hard way. ;D

Thanks for your feedback.

Consider donating to these package developers, we will feel fantastic too. ;)

Does using these large lists slow down the routing at all? It seems like thousands of IPs in the PF tables would slow it down a bunch… ?

@sofakng:

It depends entirely on your system. Most hardware platforms will not be affected by 100's of thousands of IP's but an embedded system may. It completely depends.

Basically you want to limit your usage to less than 75 to 80 percent of your available RAM. If you're running other addons like squid then you may want to use less than 50 percent of available RAM.

In the cases where the system is slowed down by larger lists or the accumulation of large list the effects will be so small that you will not notice unless you host or depend on real time apps that are time sensitive. Other wise everything should be okay.

updated to pfsense 2.01. Removed country block and ipblock. Installed pfblocker
pfblock appears to work fine.
I am seeing a frequent messages in system log:
Dec 29 12:13:35 <user.notice>fw root: IP-Blocklist was found not running
Dec 29 12:16:26 <user.err>fw apinger: ALARM: WANGW(192.168.75.1) *** delay ***
Dec 29 12:16:36 <user.notice>fw check_reload_status: Reloading filter
Dec 29 12:16:42 <user.notice>fw root: IP-Blocklist was found not running
I do not see IP-Blocklist in the installed packages.
I see a reference in the config.xml :
–-------

<ipblocklist_settings><config><enable>0</enable></config></ipblocklist_settings>

why is IP-Blocklist trying to get restarted ?
Is there another file that still thinks IP-Blocklist is installed ?</user.notice></user.notice></user.err></user.notice>

marcelloc

maybe you need to delete its remaining script.

'/usr/local/pkg/pf/IP-Blocklist.sh'

Also look for ipblocklist scripts in /usr/local/etc/rc.d

I see a reference in the config.xml

follow these steps:

backup configuration
open /conf/config.xml
remove these entries
save file
reboot pfsense

I keep getting these messages in the system log:

But in the Dashboard everything looks good.

Increase even more Firewall Maximum Table Entries in system->advanced -> firewall/NAT

taryezveb

Ok, will try that. Now is at 3000000, will try with 4000000.

Edit: with 4000000 still getting those messages. Will keep trying until I find a number that works and report back.

marcelloc

Don't forget to see memory use in dashboard. If you are getting more then 80% may be time for an upgrade or smaller lists.

taryezveb

Memory is at 44% at the moment, I should have plenty of headroom.
