Can you do DMZ and NAT/PAT with a single public IP address on ASA5520? I have uplink in PPPoE and has only one public ip address. Would like to put anti-spam(eg. A.B.C.44) in the DMZ and there are a number of servers(eg. X.Y.Z.1, X.Y.Z.2 and X.Y.Z.3) that I want to NAT/PAT. Could someone please suggest how it should be implemented?
Two site-to-site IPSec tunnels have also been configured on this ASA.
Thanks to everyone in advance for your knowledge sharing.
