Hi there, don't know if anyone give this tip yes, but make a crontab 
when messing with iptables which shuts down iptables after lets say 10 
minutes (or enough time for you to test the new tables), so in case you 
get yourself locked out of the machine, you will have access again after 
the job runs. Yeah, experience :)
