Hi,
I have a doubt on how to do the incremental checksum in
NAT-PT. For example when I send a ping packet from a V6 network to
a V4 network, I have to removethe pseudo header from the checksum.
So I tried to usethe incremental checksum given in RFC 3021(NAT).
I filled the old data with the source address, destination
address, the next header and Length field and for the new data I
sent it as NULL and New length I set it to 0. And similarly from
V4-to-V6. But when I do a ping I still get checksum errors!!!!! I
do not find anything wrong with the logic. Please do tell me what
is wrong with my approach!!!!
Expecting a early response from you all
