Oh I see, I'll try that when my host reboots the box into single user mode. Thanks
This is the second time this happened, wanted to:
Single user mode is not needed if you didn't save your rule ( guess you couldn't save it as it would lock you immediately after you put default DROP policy without adding proper whitelist ); the lockout can be fixed just by a reboot and it will overwrite your iptables changes. Initially do a global ( or for necessary IPs ) whitelist for specific ports you want to open; then only add the default chain policy to DROP.
