Have you set IP_REASS (reassemble fragmented packets, and maybe
also IP_FRAG -> send fragmented packets) to 1 to enable the IP
fragmentation code in lwIP?
There is currently a limitation to one received fragmented IP frame,
which means as long as this is in progress of being reassembled, all
fragments of other IP frames will be thrown away. That's under
development and will soon be solved in CVS HEAD.

That could be a problem of the limitation to one IP packet
as described above.

Hope that helps.
