For NPF table and IPv6 support fixes, you need the very latest netbsd-6
branch (or -current).  Can you please update and try again?

If the problem still occurs, then can you describe the connection i.e.
what/where exactly is your source and destination?

Just to be sure -- when using "stateful", one should be aware that for
TCP connections the rule should apply for the initiating (SYN) packet.
If, for example, direction is confused and the rule is applied for the
reply (SYN-ACK) packet - connection tracking engine will not try to fix
it up and will eventually time out the state.
