hello
i don't have much knowledge to iptables and i managed to lock my self out few times
and im trying get a way to go back into the server if i missed something up
i fhave found this way:
http://www.cyberciti.biz/faq/linux-iptables-firewall-flushout-configuration-every-5minutes/
but im not really sure ifts working on my system or not, so i have to be sure
and i don't have a linux on my house or another server to test it on it
anyone can confirm me that script is working probably ? or a way to stop iptables every 10 min? so i can log back in and fix stuff

thank you

You can set a cronjob to flush iptables every five minutes if you like.


*/5 * * * * /sbin/iptables -F

You don't need a rule to allow, as long as there is no rule or policy to deny.  If the INPUT policy is set to deny, you will shop to stop the service.
