Remover reglas iptables

First, flush all these rules temporarily, as we discussed above.

# iptables --flush

Next, save the current iptables (which is empty, as we just flushed it) to the /etc/sysconfig/iptables file for permanent use using ‘service iptables save’

# service iptables save
Saving firewall rules to /etc/sysconfig/iptables:          [  OK  ]
