PfBlocker
-
@ermal:
I would recommend you to detect that you are at boot phase and do not don anything.
OK, I will find a way.
@ermal:
I generally do not like that packages call filter_configure() but rather would like packages to go and use pfctl themselves and exploit the anchors, though it needs more familiarity with pfctl.
The first generation of this package (countryblock) was editing /tmp/rules.debug. cmd asked tommyboy to change the way package apply rules.
The fist idea to improve stability was using pfsense 2.0 native options to edit rules. So current version of pfblocker create aliases, rules and then apply with filter_configure(). This was the best way I found to apply rules when users saves pfBlocker's conf. -
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.
Is it possible to put that back in please?
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.iniEdit the memory_limit cvar to 256
ie. memory_limit = 256save file and reboot

-
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. -

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!
-
After doing tests, don't forget to save pfBlocker config again.
-
Reinstalled after the max tables resize and it works a treat. Thanks! :)
-
I am getting this from time to time: 404 - Not Found
-
Can you paste the url that gets 404 error?
-
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
-
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:

I guess there's an issue with rw mounting nanobsd…
Went back to Countryblock for the time being.
Featurewise pfBlocker seems great though! -
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.

-
Very nice package, indeed. No errors to report so far. pfsense 2.0 release amd64.
-
ok, now it takes 3/4 minutes to finish boot (better than 9 minutes)
I still have those warning messages

what version are you using?
I have no embedded hardware to test it, I'm looking a way to do this using virtualbox.
-
pfSense 2.0-RELEASE (i386) / nanobsd on Compact Flash 2 Gb
pfBlocker-dev 0.1.4.1I have a 4 Gb microdrive somewhere, should I give it a try ?
-
I' ve tested virtualbox + pfsense 2.0 amd64 embedded kernel with no issues.
I'm not sure if embedded kernel will work the same way nanobsd on Compact Flash 2 Gb will do.
I found some posts on forum saying that is not easy to run nanobsd img on virtualbox, but I'm still trying..
-
hubsd,
Second test, first problem:
I've changed /etc/platform to nanobsd.
after a reboot mount -a returns:/dev/ad0s1a on / (ufs, local, noatime, read-only, synchronous) devfs on /dev (devfs, local) /dev/md0 on /tmp (ufs, local) /dev/md1 on /var (ufs, local)So, read-only file system.
installed and configured pfblocker with no issues.
after a reboot,
I got the same error:php: : The command '/sbin/pfctl -o basic -f /tmp/rules.debug' returned exit code '1', the output was 'no IP address found for grep: /tmp/rules.debug:15: file "/var/db/aliastables/pfBlockerTopSpammers.txt" contains bad data pfctl: Syntax error in config file: pf rules not loaded' php: : New alert found: There were error(s) loading the rules: no IP address found for grep: /tmp/rules.debug:15: file "/var/db/aliastables/pfBlockerTopSpammers.txt" contains bad data pfctl: Syntax error in config file: pf rules not loaded The line in question reads [ /tmp/rules.debug]: php: : There were error(s) loading the rules: no IP address found for grep: /tmp/rules.debug:15: file "/var/db/aliastables/pfBlockerTopSpammers.txt" contains bad data pfctl: Syntax error in config file: pf rules not loaded - The line in question reads [ /tmp/rules.debug]:But, without saving any new config, I've looked at diagnostics-> table and pfBlockerTopSpammers was filled up normally, alias was there and firewall rules too.
So, Isn't it just a 'until boot finishes issue'?
Can you check if it happens the same way on your installation?
I know system alerts are annoying and have to be fixed but if package is still working, isn't it a minor issue?
Second problem:
boot takes 3 to 4 minutes.
it's a problem in fetch call that has no time out(or 01:15 timeout), I'll include a timeout patch to pfsense-tools.inc file on next release. -
Quick update, i exported my nanobsd config and imported it in a microdrive + classic embedded installation (so no nanobsd)
I can confirm that I have zero issue now and boot time takes 2 minutes.
So the problems I noticed are only while using nanobsd.

It slow down boot time + spam warning messages. pfBlocker works fine so yes it's not a major issue and is because of nanobsd …

Version 0.1.4.2 includes fixes to 3-9 minutes boot on embedded systems.

thanks !

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.

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.

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.
-
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!!!
-
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.
