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.
