I want to use DPM 2010 (on 2008 R2) to test backup of a Sharepoint farm in a DMZ. The MOSS App server and the SQL content db server are in the same DMZ alongside DPM 2010, while the WebFrontEnd server is in its own DMZ.
According to http://technet.microsoft.com/en-us/library/ff399341.aspx
i have to open at least 255 high ports for RPC between the two DMZs to enable communication between DPM and the protected server. However, the articles are rather general guidelines and I was unable to find any specific information on whether I really need those ports open to allow DPM to secure Sharepoint. I want to avoid opening that many ports.
So, my question is, do I need to open those 255 ports between the two DMZs or will DPM be able to secure Sharepoint without RPC/DCOM?
Your input is highly appreciated!
