Is there an IPv6 link-local address on the tun0 interface? Please show us the output of
ip addr show dev tun0 If there's no link-local address (Linux kernel bug), then you should add one manually: ip addr add fe80::1/64 dev tun0 You should use different link-locals on the two sides of the tunnel (e.g. fe80::1 on one side and fe80::2 on the other). -- Juliusz _______________________________________________ Babel-users mailing list Babel-users@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/babel-users
