I have seen postings, and heard of cases where people actually assign public IPs to servers sitting in a DMZ behind a firewall. My question is, if you only have one IP block(say a /29), how can you do this? I understand if you either 1-1 NAT or PAT from outside to DMZ, but how can you have an actual public IP on a server behind the DMZ on the ASA, on the same subnet as the outside interface?
