I guess the interaction between the two dhclient (IPv4 and IPv6) was buggy, given that while setting up my fiber7.ch dual-stack home connection I ended up with a similar problem, but with the "prepend" option. Basically, if you specify both... prepend domain-name-servers 127.0.0.1; prepend dhcp6.name-servers ::1; ...the first prepend (i.e. the IPv4 one) does not work. The prepend issue is an upstream bug which should be fixed in 4.4.0 (only available in experimental, currently at 4.4.1-1): <https://bugzilla.redhat.com/show_bug.cgi?id=643890#c10> Thx, bye, Gismo / Luca
