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
