+		iptables is the userspace command line program used to set up, maintain, and
+		inspect the tables of IPv4 packet filter rules in the Linux kernel. It's a
+		part of packet filtering framework which allows the stateless and stateful
+		packet filtering, all kinds of network address and port translation, and is a
+		flexible and extensible infrastructure with multiple layers of API's for 3rd
+		party extensions. The iptables package also includes ip6tables. ip6tables is
+		used for configuring the IPv6 packet filter.
+
+		Note that some extensions (e.g. imq and l7filter) are not included into
+		official kernel sources so you have to patch the sources before installation.
