On Thursday I wrote:
But in the meantime I suspect the problem somewhere else -- there are some peculiarities in the UDP layer that I am investigating. I'll get back when I know more.
I found it now. The client, which uses a user-mode IP/UDP implementation, sent UDP packets with invalid checksums. Using Linux's strace command, I could find out that these packets never arrived at the bearerbox. Due to some wierd effects, the behaviour was different using the localhost connection. I could resolve the problem by fixing the client.
Thanks to all who tried to help!
