Or am I interpreting something wrong? Actually, if I put the 'auto' stanza after the 'static' one, it does work (I still get the autogenerated address in the ULA prefix). Is it supposed to be order-sensitive? I can also make it work by adding 'autoconf 1' to the static stanza, and omitting the auto stanza. Richard
