I have been tasked with deploying Windows Firewall on our servers as an added measure of security. The more I investigate the ports in use on an Exchange server, the more I realize that this is a very diligent task. Has anyone ever done anything like this, or is it a general consensus that this is ridiculous and would be impossible to identify all of the ports in use.
Based on Microsoft's documentation, they claim to use this port, that port, this port "AND MANY DYNAMIC PORTS," well how is one going to drill down on the "many dynamic ports" to permit them through the firewall?
Any help, comments, or suggestions are welcome and thank you in advance!
