Hi,
I have a few servers on a vlan which have all happily auto configured
via RA, both FreeBSD and CentOS boxes. However, I freshly installed a
FreeBSD 7 box, brought it to stable, and it wont auto configure.
I'm kind of at a loss at what could be the issue. Anyone have ideas on
where to start?
Thanks
