We are up and running on Lync 2013 internally and everything works great. Now mgmt. wants me to look into getting it setup for external use and I cringe when I hear that. How much of a pain is this to get Lync setup externally? I read that you need a reverse proxy server and we have never had good luck with reverse proxy servers here. Also, what additional costs are there for external use? Do non-employees of our organization need to purchase their own client license? Or can they just download the basic client and that would work with connecting into my users? I have a lot of questions :)
Thx.
