IPv6 and ipfilter rules

[Ernie Luzar]

Hello List;

Been running my ipfilter rules since Freebsd release 3.0 with no 
problems. Lately noticed in the ipf log a high volume of inbound IPv6 
attack traffic.

I decided to add this rule to block all inbound IPv6 traffic.

bock in quick on x10 family inet6 all

What I got was both IPv6 and IPv4 inbound traffic is blocked.

Is there something wrong with the rule I used?
Is this a bug?
