Hi
I have my function hooked into pfil (2.1.6) incoming hook. I want append
6 bytes of data to the payload and route it to
the local ip. I make a copy of original packet drop the original one.
append data to new packet and route it.
I tried using fr_fastroute but ire_route_lookup returns ire_fp_mp
( fastpath header ) null if destination ip parameter is
local ip. Also i cannot depend on cache lookup as it is not reliable
though cache lookup also return NULL for local ip.
I tried an ugly way, I gave destination ip parameter a different
ip ( any known ip other my local ip )
then in the fastpath path header I just over-write the destination mac
address with local mac adddress "putnext" the
packet. But in ethereal I see Frame check sequence incorrect.
My problem is I create an udp packet wrap it in an ip packet and
I now want to route it to my machine itself
but I am not able to do that. Any help will be appreciated.
Thanks in advance
SACHIN
