I’m looking for solution on how external OWA can connect with EV using F5. I have a customer who is retiring their TMG solution and replacing it with Big-IP F5. I don’t see this gateway in the latest Compatibility Guide… but I’m still looking for input on what this configuration would look like. It's Exchange 2013 CU 13 with EV10.0.4 now and going to 12 in a few weeks. Just need to hash out this last detail. Any advice would be greatly appreciated!
