%description
|
||||
IP sets are a framework inside the Linux kernel, which can be administered
|
||||
by the ipset utility. Depending on the type, an IP set may store IP
|
||||
addresses, networks, (TCP/UDP) port numbers, MAC addresses, interface names
|
||||
or combinations of them 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.
