%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.
