We are getting ready to open up our Lync 2013 installation to our users on the other side of the firewall and I had a quick question that is going to influence how I implement the system.
Looking at articles, I see that I need a server with 2 NICs (one using an internal and the second using an external address). I was wondering if I can use my firewall to translate an external address and actually either have one or two internal addresses. Has anyone used their firewall to translate external to internal addresses for a Lync Edge server? If that is possible, then I will just create a VM (otherwise, I will need to use a physical server).
