Hi, In our current kernel, iptables doesn't work due to the error "can't initialize iptables table `filter'". I suspect that the netfilter is not turned on in the kernel. We download the v2.6.20.11 sourcecode and try to do a menuconfig but the networking packet filtering framework does not provide any option for us to select to turn on netfilter. Can anyone let me know what patch files I need to add to allow me to choose this netfilter feature? thanks peng
