/include/linux/netfilter.h /include/linux/netfilter_ipv4.h ... start with nf_register_hook(), nf_unregister_hook(), nf_hookfn()... For an understanding of how hooks are called, search for NF_HOOK, and the IP hooks NF_IP_PRE_ROUTING, NF_IP_LOCAL_OUT.... in the linux kernel source. You can also look at ARP hooks and bridge hooks. The later is useful in the event you seek network transparency.
