netfilter/Knetfilter

["Irish, Jon D BAE SYSTEMS" <Jon.Irish@AMD.ARMY.MIL>]

I recently upgraded my kernel to 2.4.20. During the selection process, I picked the following from the network options:
*	Packet Socket
*	Socket filtering
*	IP Multicast Support
*	Network Packet Filtering

Every time I try to run knetfilter, I get this error: "You have not supported netfilter in your kernel.Please recompile your kernel and netfilter tools." What options am I missing from my kernel? I thought that Network Packet Filtering was all that was required.
