My best advice here is to do what I did - which is | to disable 'pf' entirely and see if it works then. When it does you know | the IPv6 config is correct and can then work out which rule in 'pf' is | stopping it working when enabled. Sorry, but I van't think of anything else | right now, and I guess that may not be an option on a production machine. Well, stopping the firewall a few seconds can't do really bad things, and, well, pfctl -d, wait a bit, try again, still no luck... The network is pretty simple, gateway : em0: flags=8843 mtu 1500 options=b inet6 fe80::207:e9ff:fe0e:dead%em0 prefixlen 64 scopeid 0x1 inet6 2a01:678:1:443:: prefixlen 64 inet6 2a01:678:100:: prefixlen 48 first machine : bridge0: flags=8843 metric 0 mtu 1500 inet6 fe80::2d0:dead:beef:cafe%bridge0 prefixlen 64 scopeid 0x4 inet6 2a01:678:1:443::443 prefixlen 64 destination machine : fxp0: flags=8843 mtu 1500 options=8 inet6 fe80::2b0:d0ff:fee1:c05f%fxp0 prefixlen 64 scopeid 0x1 inet6 2a01:678:100:2:: prefixlen 48 All three ports on a switch. I don't believe it's a problem in if_bridge(4) because it's the same if I try from outside my network. -- Mathieu Arnold --==========150136CBDB2B990184B3========== Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEUEARECAAYFAkihfd4ACgkQJqR8av5thQ95eQCXfNSt9BUdm72ndB5PkWN75bUh YwCfXjQomi94vcBGbVDBJ/RxlmGuF4E= =LsX4 -----END PGP SIGNATURE----- --==========150136CBDB2B990184B3==========--
