Hi Patrick,
With regards to this particular issue, one thing that caught me when I started using RSTs was that the packets get sent using the routing table. In my case I had a stealth bridging firewall that I had set up with flexresp, but found that, although Snort was listening on br0 (eth1 + eth2, no IPs assigned), RST packets were being emitted on eth0 (my management interface, where my only IP was assigned). As a result, my stateful firewalls on the management network were dropping the packets.
Double-check that the RSTs are being sent out the interface you think they're going out through.

Also, are there any known bugs with connection resets? I think the
reset packets may not be getting sent to both ends of the connection or
else might not have the proper source port set.
