I'd like to remove an ISA server from the DMZ of an ASA 5510 and just use the ASA to terminate the OWA traffic.. The users that will be using the OWA will be mobile windows clients. We currently use LDAP Auth so would like to use that.
Can this be done? If so is there any doco for this?
OWA is a feature on the Exchange server, so I do not believe it is possible for the ASA to terminate the OWA traffic. However, you can configure NAT and open up the needed ports on the ASA to allow traffic from the outside to reach your Exchange server via OWA.
