Out of interest, you didn't say if you tried adding manually a route in you= r=20 /etc/conf.d/net for the link-local address space to see if it works: routes_eth0=3D" default via 192.168.123.254 169.254.0.0/16 via 169.254.1.1" <=3D=3DAdd this route for 169.254.0.0/16= =3D=3D =2D-=20 Regards, Mick --nextPart1969548.ModlkWQloz Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAABCAAGBQJU8tfyAAoJELAdA+zwE4YegGYH+QGNmJ4M/MhO4XFuj6kbU31m AhXwpmOJBOta2LAWdiEGPq1xjdMkXIZtD7SXzIoo8Qm3JtNDG1KkD/APWOFohJ3k dgzwMp0j+vixmvJsDxhL2QJ5vylat7554ERF4USrDCi6nm8UIA3o9wbyzuBaRqHW k7GMNfVQkvBCOhgdBVae7VXBKixJyQ+6OQu37PPrNWhnWpk2ev4nsPOhzRgOctM9 xpp8eWIesLSukPEL0LFTm8XeHwT8ZVZRWqUiVoFjQIpCQKMNJMgtndnnCUanufFS np3TCIgopmAQ4yokvcMFJlJRGP4rbA5UV+tDtiCIHYzHq/g844czIvh8ym7AWLU= =fUxC -----END PGP SIGNATURE----- --nextPart1969548.ModlkWQloz--
