+ 1. IPtables
+
+ Redirect of specific traffic to chain specified in the configuration.
+ If the 'chainname="BLOCK"' option is used and you are interested in SSH attackers (tcp/22),
+ it's necessary use these commands:
+
+ iptables -N BLOCK
+ iptables -I INPUT 1 --protocol tcp --dport 22 --jump BLOCK
+
+ 2. IPset
+
+ Initialize the new set and create a blocking rule in iptables.

+ ipset --create BLOCK iphash
