Patch Management 7.1 SP2 - What internet sites do I need to unblock to download Win updates and PMImport.cab?

Hi all,

All of our servers do not have Internet access, but we are making exception for our Altiris SMP server to have limited internet access.  In regards to Patch Management Solution, what sites do we need to have access to successfully 1) Download PMImport.cab, 2) Download all Windows Updates, 3) Download Adobe updates etc.

Thank you in Advance.
