Lync 2013 Desktop Shareing

Question

Hi all
this is Lync 2013.
When desktop sharing between 2 external users( Connecting from Internet) will it be P2P or will it go via FE servers ?
When desktop sharing between 1 internal user and 1 External user, will it be via FE server ?
regards

Answer 1

Sorry about that, I guessed this was common knowledge.
NAT means "Network Address Translation" which is a difficult term for saying that someone is for example sitting at home behind a Router connected to an ISP with one public IP Address and shares the internet access with other devices connected to that user
(essentially enabling all those devices connections to internet without the need of having multiple public IP Adresses)
The process works by hiding the device real IP and replacing with the router Public IP address when it crosses the router and ther router keeps track of Ports and sessions that the different devices have so it knows how to send traffic back to the devices.
A side effect of this is that there is no way of someone on the internet connection can see your IP or contact you directly.  Lync does have a process to try to enable direct communication between clients behind a NAT but that does not guarantee
this will always work, there are cases where it will work and cases where it will never work.  In case it does not work Lync will bridge the connection at the Lync EDGE server.
I hope this explains it better
