It is possible on some operating systems, although probably not on all. I just
confirmed that I can run with an alias interface on a Linux 2.6 system.

The message you reported says that the DHCP server thinks that the interface is
configured with address 0.0.0.0.

If the message is correct, that might be the reason it is failing.

If it is not correct, maybe you can show us an ifconfig output, and/or tell us
more about the specific setup?
