yesterday i got my self locked from my own server. and than i try to flush iptables from another server to get it unlocked as this question response 3 times fail then lock
After that, i cannot login to the server. i ask support from the customer service and finally i can login as before.
he (customer service) reboot the server and execute iptables -A INPUT -p tcp --dport 22 -j ACCEPT and shutdown the firewall.
and now i want the firewall back as before it flushed.
is it possible to do that? and how to do that?
i read from other forum, they said with just reboot the machine it the ip table will restore to previous state. is it right?
