This section provides guidance on how to configure a Reverse Proxy solution.

In most cases, Lync is run in a High Availability (HA) configuration as a critical application. Therefore, use of a virtual or physical load balancer is required. The Virtual LoadMaster and hardware LoadMaster systems both provide a supported Reverse Proxy solution.

First, the necessary Lync Web Service information needs to be gathered, for example:

Address (FQDN and Listener IP)

Listener IP

Internal IP
