I have no idea if it's | actually a problem, but it gives me a bad feeling.... Well, hum, I'm pretty sure there's no network and broadcast addresses in IPv6. Routing works, ping works, only neighbor discovery does strange things, from time to time. I'm a bit reluctant to change all that the eve of my going on vacation. I just discovered that I can't ping6 ff02::1%em0 on the gateway, well, I can, there are answers comming back, but, hum, they don't seem to sink in, and ping6 don't say anything. I'll investigate. -- Mathieu Arnold --==========3674126C94FE99998E55========== Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEARECAAYFAkihh6wACgkQJqR8av5thQ8aTACfVB7QFAyRDF2t1Ih6h0jTyXD6 MtEAn0NpdAJQVnqVJpxVduA4uebcDCeW =mgEE -----END PGP SIGNATURE----- --==========3674126C94FE99998E55==========--
