NAT an IP address to an internal host (public IP is not assigned to any ASA interface) - internal host is a web server
Posted on 2013-12-29
Hi I was told by engineer that ASA can do this due to proxy arp. I need to nat a public IP (this public IP is ours - routes into our DMZ, The IP I wish to use is not assigned on any active interface however)
My understanding of nat on the asa is basic - just nat (inside) (outside) interfaces etc then port eg 80
How do i achieve this without (inside) (outside) (dmz) which are interfaces. Do I just create an object and nat that ? The IP is in the DMZ range so do I nat to that the DMZ interface on the ASA- even though IP address is not assigned to an any server IN DMZ or asa interface. ? If so can someone provide a nat command example to follow please?
