I have what I think is a simple setup and problem. I have many internal servers, two of them are Lync and Exchange with private IP addresses on them. How does one setup the ASA (5512) to allow the communication for two things:
1 some internal private IPs use the same hosts - so the ASA fails when you tell it to forward the same ports?
2 with port forwarding how to handling something like Lync that has about 20,000 ports needed to map to its inside?
Currently I have things like OWA working by forwarding port 443 to the correct private IP. Obviously this a busy port and a issue. In some places you can reassign HTTPS to another port but there has got to be a better way.
much appreciate of any help/guidance....
