To set the default policy to DROP (instead of ACCEPT) for
the built-in INPUT chain which processes incoming packets,
add or correct the following line in
'/etc/sysconfig/ip6tables':
':INPUT DROP [0:0]'
If changes were required, reload the ip6tables rules:
'$ sudo service ip6tables reload'
[drop_incoming_pkt/accept_incoming_pkt]
In 'ip6tables', the default policy is applied only after all
the applicable rules in the table are examined for a match. Setting the
default policy to 'DROP' implements proper design for a firewall, i.e.
any packets which are not explicitly permitted should not be
accepted.
