Hi,
Can somebody tell me why function ptr ip_nat_ptr is used in ip_input() of
/usr/src/sys/netinet/ip_input.c file. as natd uses divert sockets and the firewall
has to explicitly divert all packets to the port on which natd is running ,what
significance ip_nat_ptr holds.
Please clarify my doubts,
Thanks ,
Aravind.
