iptables vs ip6tables

ip6tables is used to set, manage and check the table of the IPv6 packet filter rules of the Linux kernel. There is a possibility that several different tables are defined. Each table contains a built in chain. It can also contain user-defined chains. Each rule specifies what to do for matched packet. This is called a “target” and sometimes jumps to a user-defined chain in the same table.

# service iptables stop
# service ip6tables stop
# chkconfig iptables off
# chkconfig ip6tables off
