I just upgraded my cable modem service to the Comcast Pro service so I can get rid of my old 144K DSL Line and still have 'persistant' IP's I use to host my own small email, web, etc server. However, the service gives you 5 ip addresses from DHCP and they are not staticly assigned. The problem is that I would need my public interface to get 5 DHCP leases then proxy arp those for my NAT's. I have never heard of this being possible since the DHCP server is assigning them to a MAC Address. So I need a public interface with 5 different MAC Addresses on 1 firewall or 5 firewalls to secure 5 servers, each having a seperate public ip/internal ip NAT.
My question is this: I know Astaro can have multiple IP's on a ethernet interface, but can they be DHCP and then spoof the MAC or are they just static addresses you add? The other option I can think of is to have 6 NIC's on the firewall, each one with DHCP enabled. Not sure how that will effect routing though if 5 of the 6 interfaces all have the same IP range/subnet mask.
Any help would be appreciated. I've got a half dozen old Pentium 166's laying around that I could do the 5 firewall option but thats a big pain in the ***.
