IP-Blocklist

0.1.6 Release Notes:
Introduction
IP-Blocklist is a global IP blocking package. The package is designed to import IP lists in the format of “Descption:xx.xx.xx.xx-xx.xx.xx.xx” This is the format that PeerGuardian2 uses. Therefore, this package is a PeerGuardian2 solution at the gateway/router level.

What’s New
0.1.6 doesn’t overwrite or interfere with your existing firewall rules. 4 lines are inserted into the pf config file that allows pf to block the IPs in your list. pf is resync’d with the pf config file. Building a pf table allows you to block thousands and thousands of IP addresses in a matter of seconds. The manual IP blocking feature still uses IPFW

Security considerations
This package gives you the power to completely block a range of networks and IPs, be careful not to block DNS servers, internal IPs, and other IPs/Networks that you rely on.

Contributed Software
Perl IP to CIDR converter edited for this package. Original code at: http://www.bluetack.co.uk/forums/index.php?showtopic=18081&pid=84901&st=0&#entry84901
IP2CIDR Perl script from Guy Patterson. Website: www.nullamatix.com

Requirements
This package installs Perl and the NET CIDR Perl module. Lists can be found at iblocklist.com

Upgrading from any version to latest
Please uninstall your previous version before installing the new version. Upgrading without uninstalling will lead to unknown/unwanted effects.

To-Do list
Script does not apply blocklist on startup.
Large lists hit a hard limit set by the pf config file.

Have you been able to get one of the dev to add it to the package manager? My dumba$$ did something to the globals.inc file and now i can't access my box…lol... have to wait till i get home and do a quick rebuild.....

tommyboy180

I am still trying to get a hold of a dev. I have emailed them and contacted them on the freenode chat room.

I can email you a globals.inc file if you need. PM me.

Version 0.1.9 is complete.

Changes:

If enabled the block list will apply on start-up.
Fixed "out of memory" errors. You can now have a lvl1,2,&3 list applied at the same time. New limit is 900,000 entries
Removes duplicate entries to speed up process

This version is considered very stable. I have tested on 1.2.2 and 1.2.3.

When I try just the level1 list, i get this error after a min or 2 of clicking save/update

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 81 bytes) in /etc/inc/util.inc on line 381

The status states it is running but the Enable IP-Blocklist is not checked, even tho i checked it before clicking on save/update

I've tried the level 2 and level 3 list and did not get the same error… Worked like it should I think...

tommyboy180

Yes. The web server runs out of memory. You can increase the memory limit in the php.ini file

The script still operates as it should and the lists still get applied as they should. The only downside that I can see from this error is that the "Enabled" checkbox seems to not be checked when in fact it is.

I chose not to have the package edit the php.ini memory limit because I didn't want to crash a pfsense install that had limited memory.

You are correct that it does work as it should even with the error.

Cino

Thanks again!!! Would you happen to know which php.ini file to change and how would I get it to stay after a reboot?

Will this automatically update the lists like PeerBlock/PeerGuardian does?

Just to be sure where exactly do the tarballs content go? And will the howto instructions break the current pkg system?

tommyboy180

This package gets updated on start-up and every time you click save.

The tar archive is if you wanted to experiment without the package system. Just change your package system settings back to default after you install. This is only temporay until a DEV is kind enough to commit my package.

tommyboy180

IP-Blocklist is now available as a package!

@tommyboy180:

Are you referring to the package itself or the blocklists? Is there a way to automatically update your blocklists daily or whatever without restarting the firewall?

tommyboy180

On start-up the blocklists will get updated.

To have the lists updated on a specific schedule you have to create a cron job. The file to run is /usr/local/etc/rc.d/IP-Blocklist.sh

Sweet, thanks. That would be a feature request from me then; GUI based scheduled blocklist updates :)

I would be interested in being able to tie this into Fail2Ban. Do to do we'd need a simple API to add items to the list. For example a RESTful api:

/api/blocklist/add?ip=1.2.3.4&expire=3600&key=kjdsft34jk8

This wouldn't play nice with the NanoBSD install until I added lines to mount the CF card for R/W access and then back to R/O access at the point of where it writes to the lists.txt file in ipblocklist_list.php.

I have this problem in pfsense 2.0 beta 1

Take a look at Cino's post above.

Hello,

Sorry, but i can't get it to work.
I'm using pfSense 1.2.3 release and IP-Blocklist 0.1.9.
The box is used in a multi-wan context, plus some IPsecs, plus PPTP, plus Squid/Squidguard (use only on WAN1).
I tried to use the following list : http://list.iblocklist.com/?list=cn, and it seems to be well added in the GUI, but the status is always shown as "NOT running" in red.
I enabled/disabled the module, saved/updated, there's no error such as the memory error, and no message in the logs.
Any idea ?
Thank you.
