Preparing your network for installation

Published: December 16, 2009

Applies To: Forefront Client Security

Before installing Client Security server components, you should verify that the appropriate network ports are open on any server firewall. In some cases, firewalls between Client Security servers should be disabled.

The following tables list the network ports and protocols that are used for communicating between Client Security servers and between the distribution server and Microsoft Update. Depending on the type of firewalls you use and the location of those firewalls, you may need to open these ports.
