Extra info: All network cards are working fine. Except that the ipchains is working instead of iptables.
I will need to use iptables to take advantage of the netfilter capabilities however the iptables would not start with error like: /lib/modules/2.4.7-10/kernel/net/ipv4/netfilter/ip_tables.o: init_module: Device or resource busy /lib/modules/2.4.7-10/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.7-10/kernel/net/ipv4/netfilter/ip_tables.o failed /lib/modules/2.4.7-10/kernel/net/ipv4/netfilter/ip_tables.o: insmod ip_tables failed "James P.
