First of all apologies for the rather long title, but I felt the need to state the full scenario in one sentence.
I have been struggling a little with this scenario for a while, and although it is briefly described as a supported and “no-brainer” setup in the TechNet documentation you come across it proved much harder than I first anticipated when recommending this design for a small sized customer. It also struck me, in regards to the previous reference to TechNet, how poorly documented this actually is – and inspired me to shed a little light to this dark corner of Lync Server installation.
As this post, as usual, turned out to be longer than I wanted it to be I decided to break it into two: This one being sort of the background or explanation, the next one will elaborate on the how-to’s.
Happy reading!
