Let’s Encrypt and Skype for Business

For my home lab I’m using the free certificates from Let’s Encrypt (Let’s Encrypt is a free, automated, and open Certificate Authority). The certificates from them have 1 big limitation, they are only valid for 3 months but you can renew them “almost” automatically. As explained In my blog last week about “Skype for Business environment running with just one public IP” I’m running my Reverse Proxy with IIS ARR (Application Request Routing).
