Is netfilter hook and iptables rules are same?

["Ganesan Natarajan" <natrajputra@xxxxxxxxx>]

Hi all,
         What is the difference between the netfilter hooks and iptables rules?

Are both same?

If different, how the packet traverses through the stack?

What is the behaviour, if we insmod a netfilter hook at PRE_ROUTE to
drop the packet and insert a rule using iptables at PREROUTING chain
to QUEUE the packet?

Thanks
Ganesan
