Subject: How to avoid fragmentation

Message-ID: <435D40ED.1080109@speedy.com.ar> (raw)
Hi all!!
I'm developing a new target extension and I need to add some extra data
and headers in TCP/UDP packets. But I'm having a problem: fragmentation.
In the header developed by me I add a new checksum field to verify the
integrity of that header. This works fine while there is no
fragmentation. If the packet is fragmented I can't recalculate that
checksum.
Does someone know how to correct or avoid this? Or have experience with
fragmentation?
Thanks a lot!
