I am sending command line commands to the Iptables. Once I set these rules I connect to my router. on connecting all the rules I just add is removed and only the original firewall rules that tails has added is present. I can not save and restore the rules as I am using a DVD. How can I send commands to Iptables and make them stay without getting deleted after I have connected to the router? I can added rules after the connection is made but I would like to have the firewall rules set before the connection.
