Hi,

  I have been trying to understand the way NAT in FreeBsd works and its flow. In the files ip_input.c and ip_output.c there is a reference to NAT hook which is of the following form

 (*ip_nat_ptr)(&ip,&m,m->m_pkthdr.rcvif,IP_NAT_IN)

  ip_nat_ptr is a pointer to ip_nat_t whose decleration is in ip_fw.h. But I did not find any where the definition of this function.

  Also i could not find the decleration of ip_nat_init nor its definition.

  Please help me in locating these functions.

Raghuveer.
