custom firewall configuration

[Greg Golin]

Romeo,

service iptables save

This shall save the custom rules you apply to /etc/sysconfig/iptables
so that when iptables starts, it reads the new rules you have applied.
I suggest adding a cron job that flushes the rules every five minutes
for the duration of configuration just to make sure you're not locked
out.
