Interesting, what are the kernel versions in these Wheezy and Jessie systems? Does the problem (with 'ip -6 r') appears also when BIRD is not running? I wonder what factors are specific to this problem. I remember there were a similar report or two few years ago, but these reports are too uncommon to be an universal problem in IPv6 Linux forwarding. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: [email protected]) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
