Public IP's behind ASG 8

Hi,

My apologies if someone knows of a thread that addresses this. I read a number of threads regarding public IP's and they usually describe solutions where there are 2 IP's required to get to the actual server: the public IP and then use of NAT to a private IP (usually using the 192.x.x.x address space).

What I would like to know is if it is possible to use only 1 IP setup on the internal server that can be mapped to be exposed to the outside world?.

I currently have a DNS server properly routed so that when I do an external lookup test, the correct IP address is shown.

Thanks in advance for any assistance.

BTW, I prefer not to add a DMZ as my server is a small form factor system and I do not have any spare interface for the DMZ
