Exchange 2010: Network Communication Table

2011-07-30 1 min read Exchange Exchange 2010 Microsoft Networking Security System Administration Zachary Loeber

I figured I’d post the massive table of firewall rules I compiled for my Exchange 2010 firewall generation script. It has both the source and destination roles for many aspects of an Exchange environment. Where there are ???’s is where I’m simply not certain (mainly around encryption between certain roles). If anyone spots any mistakes or omissions please let me know and I’ll update the accordingly.
