According to iptables user manual, we are suggest to do filter work only in iptables filter table. There are three chains in it: INPUT, FORWARD, OUTPUT. Why does this module restrict the hook points in NF_INET_LOCAL_IN & NF_INET_PRE_ROUTING. The PRE_ROUTING chain does not exist in filter table. Can you explain it?

I want to filter DNS traffic in a router. Can I use this module in FORWARD chain?
