I am currently trying to access my internal OWA site hosted on our Exchange 2003 server from an external IP over HTTPS. The external IP exists on our "internet" interface and the internal IP exists on our "inside" interface.
access-list Internet extended permit https any host EXTERNAL_IP log
static (inside,internet) tcp EXTERNAL_IP https INTERNAL_IP https netmask 255.255.255.255
I cannot see the traffic getting through, nor being blocked on the ASA
