ipset

Description

IP sets are a framework inside the Linux kernel since version 2.4.x, which can be administered by the ipset utility. Depending on the type, currently an IP set may store IP addresses, (TCP/UDP) port numbers or IP addresses with MAC addresses in a way, which ensures lightning speed when matching an entry against a set. If you want to: - store multiple IP addresses or port numbers and match against the collection by iptables at one swoop; - dynamically update iptables rules against IP addresses or ports without performance penalty; - express complex IP address and ports based rulesets with one single iptables rule and benefit from the speed of IP sets then ipset may be the proper tool for you.
