Indeed, that or using iptables -I to insert the other rules... or better yet, do as you say and put the new rules above the DROP and rather than using a script, use /etc/sysconfig/iptables for the configuration and use iptables-restore </etc/sysconfig/iptables to apply changes very fast... What's odd though is that a DROP wouldn't result in a connection refused error, you'd need a REJECT for that, with DROP it would just be a timeout... d
