Your network is configured as shown in the exhibit.
You need to ensure that all remote users can download the address book by using Microsoft Lync 2010.
Which TCP ports should you open on Firewall2?
A.
80 and 443
B.
80 and 8080
C.
443 and 4443
D.
4443 and 8080
I think that answer A is correct. On the TMG has to be opened 80 and 443 port and redirected to internal server (Director or Front-End) on 8080 and 4443.
Just look at Protocol Workloads Poster at http://www.microsoft.com/en-us/download/details.aspx?id=6797.
