H A Dipfw2.cdiff 152923 Tue Nov 29 13:25:09 MST 2005 ume We couldn't specify the rule for filtering tunnel traffic since an
IPv6 support was committed:

- Stop treating `ip' and `ipv6' as special in `proto' option as they
conflict with /etc/protocols.

- Disuse `ipv4' in `proto' option as it is corresponding to `ipv6'.

- When protocol is specified as numeric, treat it as it is even it is
41 (ipv6).

- Allow zero for protocol as it is valid number of `ip'.

Still, we cannot specify an IPv6 over an IPv4 tunnel like before such
as:

pass ipv6 from any to any

But, now, you can specify it like:

pass ip4 from any to any proto ipv6
