Xtables-addons is a set of extensions that were not accepted in the Linux kernel and/or main Xtables/iptables package.
It superseded the earlier patch-o-matic(-ng) package in that no patching and/or recompilation of either the kernel or Xtables/iptables is required. However, do see the INSTALL file for the minimum requirements of Xtables-addons.
