Lync 2013 Firewall Rules: Cross-post

If you're lucky enough to be the Messaging Administrator and don't have to deal with the networking side of your shop, you'll probably have to give the Lync firewall rules and specs to your networking team.

Randy Chapman, on his Lynciverse blog, has created a Visio drawing of the firewall rules and data flow for Lync 2013.  It's really sweet, and it gives a nice visual representation of the ports that your networking team needs to allow for full functionality of Lync.
