Applies To: Dynamics CRM 2013
This section describes the ports that are used for Microsoft Dynamics CRM. This information is helpful as you configure the network when users connect through a firewall.
In This Topic
Network ports for the Microsoft Dynamics CRM web application
Network ports for the Asynchronous Service, Web Application Server, and Sandbox Processing Service server roles
