 Subject:  Another IPv6 issue

I've noticed lots and lots of these in my firewall log:

23:51:26.686952 sis0 @0:43 b 2001:8b0:f:1:20c:f1ff:fee9:7232,53 -> 
2001:8b0:0:81::51bb:5120,33445 PR tcp len 40 80 -AS IN OOW

It appears that m0n0wall is blocking IPv6 DNS responses from my DNS 
server. I have no blocking rules on sis0 so I'm not sure what is causing 
m0n0wall to block them. I notice they all have OOW in the log entry - 
could that be something to do with it?
