That's the combo I use. Iptables blocks everything by default but since I have a 
website, it keeps the 80 port open. Then, the IDS watches this port for everything 
suspicious. If an alert is triggered, a new rule is added in iptables to block the offenser.
Physical firewalls excepted, IMO this is one of the best defense combo for a home server 
(and it's free).
