Using an F5 LTM Load Balancer for Reverse Proxy with Lync 2013

Ok, I couldn’t resist it… In my previous blog I wrote about publishing Lync services using a Kemp Load Master. Since I’m not married to Kemp (although you might think differently, and so does Marco 😉 I also have an F5 LTM up-and-running in my lab. Time to have a closer look at the F5 when it comes to reverse proxy with Lync 2013.

Lync Configuration

Again, in my lab I have a Lync 2013 Enterprise Edition, in the perimeter network I have a Lync 2013 Edge Server, but I will use an F5 LTM load balancer.
