IPTables - Upgrade for GeoIP Support

By Jack Szwergold • October 27, 2015

For Reference Only! 100% none of this seems to work!

This is just here for refernece for now. Might not be worth the headache to get this setup for Ubuntu 12.04.5.


sudo aptitude purge iptables iptables-persistent ubuntu-standard ufw

sudo aptitude install iptables-persistent ubuntu-standard ufw

curl -O -L http://mirrors.kernel.org/ubuntu/pool/main/i/iptables/libxtables10_1.4.21-1ubuntu1_amd64.deb
sudo dpkg -i libxtables10_1.4.21-1ubuntu1_amd64.deb

curl -O -L http://mirrors.kernel.org/ubuntu/pool/main/i/iptables/iptables_1.4.21-1ubuntu1_amd64.deb
sudo dpkg -i iptables_1.4.21-1ubuntu1_amd64.deb

curl -O -L http://mirrors.kernel.org/ubuntu/pool/main/i/iptables/iptables-dev_1.4.21-2ubuntu2_amd64.deb
sudo dpkg -i iptables-dev_1.4.21-2ubuntu2_amd64.deb

sudo aptitude purge ubuntu-standard ufw

Don’t run this command! But for reference, it would install xtables-addons-common version 1.41:

sudo aptitude install xtables-addons-common

That is out of date and won’t work with IPTables -m geoip. The way to fix this is with xtables-addons version 2.5 or higher.

curl -O -L http://old-releases.ubuntu.com/ubuntu/pool/universe/x/xtables-addons/xtables-addons-common_2.5-1_amd64.deb

Check the required dependencies like this:

dpkg-deb -I xtables-addons-common_2.5-1_amd64.deb | grep Depends

The output is something like this:

Pre-Depends: multiarch-support
Depends: libc6 (>= 2.4), libxtables10

And then install it like this:

sudo dpkg -i xtables-addons-common_2.5-1_amd64.deb

If you somehow need to uninstall this version dpkg install of xtables-addons-common, just do the following. First find out the package name like this:

dpkg -l | grep xtables-addons-common

Knowing that just uninstall it like this:

sudo dpkg -r xtables-addons-common:i386

sudo aptitude install module-assistant

sudo module-assistant prepare

sudo aptitude install linux-headers-3.13.0-66-generic

sudo module-assistant --verbose --text-mode auto-install xtables-addons

This downloads the GeoIP CSV files:

sudo /usr/lib/xtables-addons/xt_geoip_dl

Install this tool to get import the CSV files into Xtables so it can be used by IPTables.

sudo aptitude install libtext-csv-xs-perl

Create the GeoIP directory if it doesn’t already exist:

sudo mkdir -p /usr/share/xt_geoip

Now run this command to build the GeoIP databases for IP ranges:

sudo /usr/lib/xtables-addons/xt_geoip_build -D /usr/share/xt_geoip *.csv

The databases will be built in the following directories:

ls -la /usr/share/xt_geoip/BE
ls -la /usr/share/xt_geoip/LE

Check if the GeoIP module is installed:

sudo cat /proc/net/ip_tables_matches

Check if the GeoIP module was installed:

sudo iptables -m geoip --help

A test ban for (sadly) all of China:

sudo iptables -A INPUT -m geoip --src-cc CN -j DROP
