IP sets are a framework inside the Linux 2.4.x and 2.6.x kernel,
|
|
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.

IP sets was written by Jozsef Kadlecsik and it is based on ippool
|
|
by Joakim Axelsson, Patrick Schaaf and Martin Josefsson.

This requires kernel-source.
