Moving to a NEW ISP - Cisco ASA 5510 - 3 interfaces - NAT - block of addesses

We are moving to a new ISP, but the requirements differ in that the provider only offers a /30 bit subnet for our CISCO ASA 5510 WAN Interface connecting to the ISP upstream router.


They did assign a block of 14 IP addresses to use (/28), but I am guessing I will need to translate this pool of addresses from behind an available DMZ interface.  


Our current physical/logical the address block is a /28 bit mask and allows us to translate without the extra perimeter - much easier, but this is going bye-bye.

I did get the DMZ and LAN traffic to communicate, by simply using a nat exemption.

How do I translate and get the [10.200.200.x] servers behind the DMZ to provide Internet request, using the 100.100.100.96 /28 (.97-.110) usable?  


To allow full LAN Internet access, will I simply translate the LAN traffic (192.168.100.x) to the WAN interface IP, or do I use one of the addresses out of the block of 100.100.100.96 /28?

I also have 2 site to site VPNS - that would need to be reconfigured to connect to the proper endpoint.  Would I connect them to the  /30 PUBLIC IPS or one of the /28 PUBLIC IPs?


Of course, I will repoint my PUBLIC DNS records, once this is square.
