IP-Blocklist

[tommyboy180]

Just like PeerGuardian2 the IP-Blocklist package can block ranges of IPs from lists or manual input. This is a Global IP blocking package.
Ver. 3.5

Info:
This package uses the pf (pfctl) to block IP addresses. For each IP range or list added a pf table is made and applied to the firewall to prevent traffic from being sent to and traffic from being received from the target. You can whitelist ranges by entering a list from sites like iblocklist.com.
Tested on 1.2.2, 1.2.3, and 2.0 RC3 with FF & Chrome. IE not supported.

Limits:
Lists can have any extension BUT if the list is compressed only .gz is supported. CIDR is coming for pfsense 2.0
Long lists take more ram (not much)
Increase your php memory limit in /etc/inc/config.inc to avoid issues if you use many lists

Format
The lists must be in the PeerBlock or PeerGuardian2 format.
Single IP Example: NAS:192.168.1.110-192.168.1.110
Range IP Example: HOME:192.168.1.0-192.168.1.255
CIDR Ranges will be in future versions for 2.0 only.

FAQ:
Q: How do I know if the list got applied?
A: The package web interface will display the current status.

Q: I notice a performance drop with network traffic after applying
A: When applying the list at the system has to download and process the list. This should only take less than 2 mins.

Q: I have the "Enable" check box checked but I don't think its blocking any IPs
A: Any Errors will be at the bottom of the page when you press Save/Update

Q: My list site only give dynamic links to lists (I can't get a direct link to the file)
A: You need a direct link to the file in order for the package to work. Use a download manager like FF has. Download the file then go back to the download manager and copy the file link. Paste that into the package. File upload may be in the future.

Q: Where can I get lists to block SPAM and other bad IPs?
A: http://www.iblocklist.com/lists.php

Q: I think I can improve your package or add features, how can I help?
A: Send me a PM

Q: I'm running embedded and it's not working
A: http://forum.pfsense.org/index.php/topic,24769.msg170314.html#msg170314

Features include interface filtering, outbound access, whitelisting, and much much more!

1.2.2

I can't seem to locate this package, is it called : 'URL Table Aliases'?

[tommyboy180]

Version 0.1.5 is complete. This update uses pf tables as the blocking method. This brings a huge performance boost but uses more ram. New screen shot added.

Package will be committed soon. Just trying to get a hold of a DEV to commit. I also have some new updates to the package, one update will let you process a level1 list in 2 seconds and apply it immediately!

Thank you jim-p for the idea.

You can download the packages right now while you wait for a DEV to commit them. http://www.tomschaefer.org/temp/pfsense/packages/

i installed 0.1.5 and when i try to start it i get this error: ipblocklist.conf:8: cannot define table ipblocklist: Cannot allocate memory

Running 1.2.3.. Lots of add ons, squid, squidguard,snort. i have 1.7g free of memory

[tommyboy180]

I am working on an update. I think the big lists are hitting a ceiling. I should have 0.1.6 out here soon, at-least within the week.

[Cino]

Its a limit on the system i think

pfctl -sm

states        hard limit    10000
src-nodes    hard limit    10000
frags        hard limit    5000
tables        hard limit    1000
table-entries hard limit  200000

would need to increase table-entries somehow… I'm playing URL Table Aliases and notice I get the error with Level1 list

[tommyboy180]

Update 0.1.6 released.

[Supermule]

Release notes??

[tommyboy180]

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.

[tommyboy180]

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.

[Supermule]

Nice work Tommy!!

Have you had any luck getting hold of the dev's??

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?

[peterclark4]

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

[g4m3c4ck]

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