Greetings,
        I have just upgraded my linux box to RedHat 7.2 in order to
use Iptable.
But I'm unable to load the module.

if i give the command modprobe ip_tables it gives the following
errors:
/lib/modules/2.4.7-10/kernel/net/ipv4/netfilter/ip_tables.o:int_modules:Device
or resource busy.
/lib/modules/2.4.7-10/kernel/net/ipv4/netfilter/ip_table.o:insmod
/lob/modules/2.4.7-10/kernel/net/ipv4/netfilter/ip_tables.o failed

Thanks in advance to all who reply.
