Just a basic Dynamic PAT that uses the public IP address on the "outside" interface and accept the source addresses specified inside the "object-group" and the source interface for them can be "any" (so that we can do Dynamic PAT with one command to all of the internal interfaces)
I am not sure if there is a bug involved with your problem. I had an ASA with 8.4 software just stop performing NAT even though it was using a NAT Pool + PAT overload. It went through the pool and ignored the PAT for no obvious reason.
I am not sure would a reload at some point help at all or trying other NAT configurations for the Internal interface if its not working at all at the moment.
Have you been able to determine anything from device logs while attempting connection?
