Hi Kieran,
hi Simon,
thank you for your thoughts on my problem. So far I have solved the
problem by simply setting IP_REASSEMBLY and IP_FRAG both to "0". That
way no fragmented packes are processed at all and since I am only using
a tftp, this shouldn't happen anyway and it works for me.
Thanks anyway. Maybe one day, if I get the time to do so, I might try
lwIP 1.4.
Best regards,
Dennis

As long as I stay below 1536, everything just runs fine.
I think it could just be that the ping code in that release assumes that the
whole datagram will fit in a single packet. When you exceed the MTU the
datagram will be fragmented and I doubt the code has been written to cope with
that.
Hmm, I also thought about that, but 1536 is already bigger than the MTU, isn't
it?
I would try and see if (i) the more recent versions of lwIP do what you want
Definitively. And if not, it will be much easier to try and reproduce the
problems you are seeing.
Simon
