Is there a way around this, or is it not > possible to serve IPv6 addresses over if_bridge interfaces? It's totally doable; you just have to assigned a link-local address to the bridge. There are some reasons why one isn't defined by default, which somebody more knowledgeable about the challenges in the implementation can highlight. Here's my configuration from rc.conf: ipv6_ifconfig_bridge0=3D"2001:470:8337:10::1/64" ipv6_ifconfig_bridge0_alias0=3D"fe80::2%bridge0 prefixlen 64" Once you're doing that, rtadvd will start doing the right thing. --=20 Chris Cowart http://www.timesinks.net/ --yQDbd2FCF2Yhw41T Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iQIcBAEBAgAGBQJLIenkAAoJEGdJs2Q92uldCHAQAIkMXQqeSWxVA67L1gTHYtqz R3VvtJOQT4FXvV6i6ouaAiPTyQ/VSXf2ZfODdCzeXbT0DdVOAIpkApymgudtvFyq kXmqjjPtMLz5RFn9XJDu7seA9jwEWUyGXsqneZsbty4xmUit5zFQZuuACDnLtptW HGTdg355vUqEz2LzLvNnm9t0ZQaCnZ73Jf4obR523D0ILV2MalqiazZLKr4URD5V TNZVdczrt875gcbV2O7qej+XM9M5mckXX6r44rCFb1TLbray70gpeO2MtMRpuGOy KCX8nXDxQPCCaomif8Lj36yzg4M22caK6Bi5kYhqgBN+ZzbfUWBZiJcH1Itfn5uV 865i9J9jvALt6bEaUsLK2HRpmKmcYV2p0p21ElwJcw5wc9ohB7dIdy0QSKJ1kxUl jA84EZgkHy2wpl5Oeam33xkWp8E21LYwmg6Uj7jzlV11EzkCc716f/Nqjh+Kcl6S vwUwhvtsFkQqnYpDsF7yhWmUCf5QtYHp/4OtWelSmZPbRE7Q/t5kH4g3CDmr6Pk7 MpGDItHBt2WdR9rppyadSEO3wtrgvjVFkZlC7cmFhZYCKQc3/54AhvHX2L866xHv RwKHfB/heCW0++tmsECs5X9ABTaBp1u7FaqUy64HVhoRHx4zjJER9Tn3a/BQv9Lt hTmcj4fKonZ88X7FvHeB =T+bJ -----END PGP SIGNATURE----- --yQDbd2FCF2Yhw41T--
