PfBlocker

[kevross33]

Great package. I have installed the latest version and I am wondering what happened to the deny inbound/outbound option? There are cases where you may block traffic to and from these countries (like countries which both do a lot of attacks, spam etc and host a lot of malware you do not want your users contacting. Is it possible to put that back in please? Thank you

I try to update very large blocklist and I get error:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 10106374 bytes) in /usr/local/pkg/pfblocker.inc on line 248

Same list work with IP-blocklist.

And after I put some smaller bloclist I get another error:

php: : There were error(s) loading the rules: /tmp/rules.debug:21: cannot define table pfBlockerblocklist: Cannot allocate memory pfctl: Syntax error in config file: pf rules not loaded - The line in question reads [21]: table <pfblockerblocklist>persist file "/var/db/aliastables/pfBlockerblocklist.txt"</pfblockerblocklist>

In special cases, you can choose alias only option and create your own rule using alias pfBlocker created.

You can also add this list into two aliases and block inbound one and block outbound other.

Not sure but I'll take a note.

The way pfBlocker downloads list is different then ipblocklist.
To increase php memory limit, edit php.ini:

php.ini location path is:
/usr/local/lib/php.ini or
/usr/local/etc/php.ini

Edit the memory_limit cvar to 256
ie. memory_limit = 256

save file and reboot

check this:

• Increase even more Firewall Maximum Table Entries

• clear ipblocklist table in diagnostics-> table

• check if the value of table-entries in /tmp/rules.debug is the same in Firewall Maximum Table Entries

• check also if table-entries is declared twice in /tmp/rules.debug

BUT
The most important thing is: read list description you are including and see if it is realy a bad guys or nasty list.

One example of not bad list is leve1 ip-blocklist file.
See its description:
Author's description:
Companies or organizations who are clearly involved with trying to stop filesharing.
Companies which anti-p2p activity has been seen from.
Companies that produce or have a strong financial interest in copyrighted material.
Government ranges or companies that have a strong financial interest in doing work for governments.
Legal industry ranges.
IPs or ranges of ISPs from which anti-p2p activity has been observed.

Thanks, I'll fix it.

Ok, package info fixed.

Thank's for your feedback

Great if we use the same table inbound and outbound, we can just use one list ;o) and create a FW rule with that list aliasname ;o)

Nice going guys. :) Having trouble having lists work. I get this when the filter reloads.

There were error(s) loading the rules: /tmp/rules.debug:17: cannot define table pfBlockerantitorrentin: Cannot allocate memory/tmp/rules.debug:19: cannot define table pfBlockerantitorrentout: Cannot allocate memory pfctl: Syntax error in config file: pf rules not loaded - The line in question reads [17]: table persist file "/var/db/aliastables/pfBlockerantitorrentin.txt" …

Going to try the fixes I see in the thread and report back. Thanks again!

[marcelloc]

After doing tests, don't forget to save pfBlocker config again.

[Quinn1981]

Reinstalled after the max tables resize and it works a treat. Thanks! :)

[RonpfS]

I am getting this from time to time: 404 - Not Found

[marcelloc]

Can you paste the url that gets 404 error?

[RonpfS]

https://12.34.56.78/pkg_edit.php?xml=pfblocker.xml

this happened at the same time as snort was misbehaving … I removed snort now

[marcelloc]

the url is fine.

while using some packages, the menu url is prefixed with /packages/something/.
when you choose other url in menu, this prefix persists, and then a 404 error occur.

This is not a problem related to pfBlocker.

I discovered a new problem today, pfsense takes more than 1 minute to finish boot (9 minutes to be accurate !)
I noticed that it's blocked most on the time on "Configuring firewall" step.

Without plugin, no problem so…

There is also that usual "Warning message" in webgui after reboot in webgui (then need to "acknowledge all")

Setup is Alix 2c3 + pfsense nanobsd + compact flash 2 GB

Widget and lists :

RAM/CPU/TABLE usage

log side, I have this messages (x10)

Same here - massive issues on 2.0 embedded (Countryblock works apart from logging though). I see loads of:

The firewall seems to be blocked then altogether. I guess there's an issue with rw mounting nanobsd…
Went back to Countryblock for the time being.
Featurewise pfBlocker seems great though!

[marcelloc]

I found a fetch issue While booting and on url table pfblocker get file function. I'm fixing it today.

EDIT

version 0.1.4.1 released with fixes in:

• boot process

• embedded platform

• url table get file package function

Many thanks for all of you that are helping us with this package.

[Hugovsky]

Very nice package, indeed. No errors to report so far. pfsense 2.0 release amd64.

[hubsd]

ok, now it takes 3/4 minutes to finish boot (better than 9 minutes)

I still have those warning messages

[marcelloc]

what version are you using?

I have no embedded hardware to test it, I'm looking a way to do this using virtualbox.
