Hi,
=20
Can somebody tell me why function ptr ip_nat_ptr is used in =
ip_input() of=20
/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=20
significance ip_nat_ptr holds.
=20
Please clarify my doubts,
Thanks ,
Aravind.
