I have a temporary outlook server sitting on an inside network and I need to set up OWA . We have a public block of IP's and I assigned a public DNS name to one of them to access the server externally. I added a route on the outside router telling it to route any traffic destined for XXX.XXX.209.9 (address assigned to OWA) to XXX.XXX.209.57 (outside int of ASA). Now I need to figure out what to configure on the asa to say whenever traffic destined for XXX.XXX.XXX.9 hits the outside interface, translate it to 10.0.0.237 and send it to the outlook server. I know this is simple natting, but I can't figure out which type of rule to use.
