I don't think you are missing something. IPv6 support in ipfw is still a=20 second class citizen (as is stateful filtering). I remember seeing a=20 mail with similar topic just recently, but can't recall on which list or=20 from whom. I don't see a PR for this - could you please create one so it's not=20 forgotten about? =2D-=20 /"\ Best regards, | mlaier@freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mlaier@EFnet / \ ASCII Ribbon Campaign | Against HTML Mail and News --nextPart8967889.SrkcK1VLGv Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) iD8DBQBHFGU1XyyEoT62BG0RAivIAJ9YlLfsIEWTekmD5lzNBTYEwgltxACePMX9 PPhJM/eTiGMeMtP0JOhK3so= =DCDz -----END PGP SIGNATURE----- --nextPart8967889.SrkcK1VLGv--
