Based solely on the error message you provided in your original post I would say assigning two or more network interfaces on the same subnet at the same time is the problem. It is not that they are both getting the same IP address but different IP addresses on the same subnet.
If you want to do such a thing you'd use the trunk method indicated earlier. <div>-------- Original message --------</div><div>From: Hrishikesh Murukkathampoondi <hris...@gmail.com> </div><div>Date:03/29/2015 7:24 AM (GMT-06:00) </div><div>To: Peter Hessler <phess...@theapt.org> </div><div>Cc: openbsd-newbies@sfobug.theapt.org </div><div>Subject: Re: Configuring DHCP for multiple interfaces </div><div> </div>Thanks for the response. I thought it is the DHCP server that must give different addresses - right ? If two interfaces from the same machine request IPs with different dhcp-client-identifiers, the DHCP server should be able to distinguish the requests. So what has to be supported by OpenBSD?
