I don't think IPFilter is IPv6-ready. There's some support but I don't
think it's stable or tested enough at this point. I may be wrong.

"ipv6" in this context means "v6 in v4". It means you're filtering
IPv6 packets based on the IPv4 tunnel end-point address, which is
better than nothing but still far from ideal.

IPFilter compiled with IPv6 support needs *two* different set of
rules. One for v4 and one for v6. The v6 set is managed with "ipf -6"
instead of "ipf". See ipf(1) :

OPTIONS
       -6     This option is required to parse IPv6 rules and  to
              have them loaded.
