The proper response would be to broadcast the offer. Ah, well spotted! I've enabled the 'always-broadcast' option (ISC dhcpd 4.2.2) to force a broadcast to be sent even when the client doesn't request it. ...

This is most strange as this setup was working for several hours and I've not had any problems with my DHCP setup before. -mj -- Michael-John Turner mj at mjturner.net <> http://mjturner.net/
