Here are the steps and couple of tips on how to install xtables-addon on CentOS and RedHat 6.4 and 6.5. It might work on all 6.X releases. In centalt repo could be found the rpms and srpms for versions 1.41 and 1.47.1 versions but I couldn’t use any on the above mentioned installations.
I wrote a puppet module which will install the xtables-addons and the update script. The module can be found on https://github.com/catalinpan/puppet-xtables-addons with some more explanations on how can be used.
For the manual installation start with updating your server or skip to next command.
