PowerShell Proxies

For this example we will configure two PowerShell proxies. One of these will be used to for the connections on the on-premises components - Active Directory, Skype for Business Server, and Exchange Server. We will use the other proxy to connect with the applications hosted in Office 365: Skype for Business Online and Exchange Online.

The decision to use two proxies rather than one - or five, or some other number in between - was somewhat arbitrary in this case; we chose two proxies mainly to demonstrate both how to divide the proxy duties between hosts, and how to combine multiple applications into a single proxy. We will install two new servers for this purpose, and we’ll call them psproxy01 and psproxy02, with the respective IP addresses of 10.5.25.240 and 10.5.25.241. After installing Windows Server 2012 R2 on both machines, we join them to the flexcorp.com domain. We can now start configuring them.
