On OpenBSD, is it possible to request multiple IP-addresses via DHCP on a single physical interface? It looks like DHCP leased addresses can't be assigned as aliases. I though of creating a virtual interface and forward traffic to the physical interface, then run dhclient on the virtual interface (it doesn't matter if the second address is assigned to a virtual interface and not as an alias to the physical interface). Unfortunately I wasn't able to get it to work like that.

Any suggestions? How would you do it?

Thanks, I tried the idea with the bridge and two vether interfaces, however it didn't work. I added these virtual interface to set skip in pf.conf, is there something more I'd need to consider? – watain Dec 4 '11 at 9:15
