Here is my rule set (with masked ipv6 addresses). There is nothing
exceptional...

block in quick on sip0 head 100
block out quick on sip0 head 101

pass out quick on ath1 head 110

block in log quick on ath1 head 111
pass in quick on ath1 from any to MY_GLOBAL_IPV6_ON_ATH1/128 group 111
pass in quick on ath1 from any to MY_LINK_LOCAL_IPV6_ON_ATH1/128 group =
111
pass in quick on ath1 from any to ff02::1/128 group 111
pass in quick on ath1 from any to MY_MULTICAST_SOLICITED_ADDRESS_ON_ATH1
/128 group 111
pass in quick on ath1 from any to ff02::1:FF00:1/128 group 111
pass in quick on ath1 from any to ff05::1:3 group 111

pass in all head 200
pass out all head 201


Only packets for this host are allowed to enter the ath1 interface and =
some
dhcp6 related packets also... Other incoming packets on this interface =
are
captured by libpcap and treated in a customized demon...
