(Not that I know the solution, but..) Iptables is a userspace utility to setup rules. Once the rule is setup, iptables itself terminates and Netfilter (kernelspace) will use the rule. Although you could add the same rule multiple times (which is a bit useless..), AFAICS there's no way to have Netfilter "running" multiple times. But you do have a point: is the OP flushing all rules/deleting all user-chains when he is restarting the firewall script ? Gr, Rob
