Hi Guys.
I hope someone can assist us.
We have Lync Server 2013 installed and have a unusual error.
This is what they have:
Internet -> Firewall -> TMG 2010 -> Lync Edge -> Front End
The Edge Server & Front End server is Windows 2012 Standard Edition.
So we are planning on moving the Edge server to the DMZ soon.
As for Lync functionality this is currently working (Note that the client did not opt for Enterprise voice.)
IM: An AD authenticated user on Lync client internal network An AD authenticated user on Lync client [works 100%]

Desktop & Application Sharing: An AD authenticated user on Lync client external network A Federated partner user on Lync client [does not work at all]
What could cause this?
Both users AD and Federated user do have permission on their own Lync policies to use these functions.
The error that we get from the federated partner logs is as follows.
ms-client-diagnostics 26 reason a federated call failed to establish due to a media connectivity failure where one endpoint is internal and the other is remote.
Any Ideas???
