If you were running tcpdump in promiscuous mode, re-run the tests with it non-promiscuous. Just to make sure the SYN is actually received by that system.

I ran the test again with "tcpdump -i eth0 -p" and then thinking better of it, with "tcpdump -i any". In both cases I was able to replicate the problem. Even with "-i any" I see the incoming SYN packets and no SYN+ACK reply.

And you do capture *all* traffic, right? Don't filter out anything.
