Multiple DHCP'd addresses on one NIC

[Aaron O'Hara]

I have my firewall connected to my cable modem with one a single NIC.
(I have another NIC for my LAN).  My public NIC is set to DHCP an
address from my ISP.

Is it possible with Fedora to setup multiple virtual adapters that have
unique MAC addresses (that I generate) that all DHCP an address from my
ISP?  This way, I'd have multiple public IPs bound to one physical
adapter.

Of course I'm going to want to firewall all the virtual adapters as
well.

The end goal is to have multiple SSL-enabled sites (which need to have
their own IP).
