Hi Kieran,
I added my debug info for one upload.
Can it be the problem, that my tcp-connection is closed after I send the
HTTP/1.1 200 OK answer to the client (line 152 in ppp_debug.txt)?
Heike
my lwipopts are...
rest is like in opts.h:

then I receive my data packets, see the added etherreal file (packets
4,5). But they are not forwarded to my http server. They get lost in the
ppp-task.
Anybody knows why???
Hmm. Could you send a copy of your lwipopts.h?
ethereal thinks a lot of the packets in the capture have bad TCP
checksums, but ethereal often gets things like that wrong and some of
the ones that get through fine are also marked like this, so I don't
believe it.
You could try turning on debugging print statements in lwIP to try and
trace what is happening to the received packets that go missing.
