Sure, I acknowledge there may be something broken there. But tcpdump on the OpenBSD box indicates the MAC addresses of the traffic received do not match any MAC address on the OpenBSD box. In this case OpenBSD should be simply discarding the packets, not transmitting spoofed RSTs for TCP conversations it is not involved in. The situation is basically the same as if OpenBSD was connected to a hub, not a switch. In that case, it would be receiving every packet traversing the local subnet. I'm not denying I might have configured OpenBSD wrong somehow - if so, any ideas as to where would be greatly appreciated.
