I have Microsoft Lync 2013 installed an working on the front end server. All is well. Recently there has been a requirement to have Android and iPhone versions of Lync working. I've configured a Reverse Proxy server.
However, what I've discovered is that Lync requires port 80 and 443 to be directed to the Reverse Proxy server. Since we have only one static IP, and no possibility of another static IP, is there anything else that can be done? I'm already using 80 and 443 for the Exchange server.
I'm looking into these static IP VPN services, but unsure how well they work.
