To create and save iptables rules the default Debian way, this is the way to go:
- create your rules using the CLI [1] iptables
- save them on the active rule by issuing a /etc/init.d/iptables save active
- create the rules for the inactive state (when booting, for example) and save them accordingly
That way, the rules will survive a reboot.
To delete a specific rule previously saved as above:
- go into /var/lib/iptables/active and take the line corresponding to the rule you want to delete and execute iptables with those parameters changing the beginning -A with -D
