If you have many rules and/or high bandwidth you should consider hipac
(High Performance Packet Classification) It uses the netfilter hooks 
and ... checkout yourself at
There is also a performance comparison with iptables ...
It exists for a 2.4 kernel. A 2.6 version is promissed for october 2004.
As we (our university have many rules 
we use it and with success

Hope this helps,
