Network ports

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.

Port usage for Client Security server components

The following table lists 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.

1433 (TCP and UDP)

None.

Management server

To collection server

Port usage for Client Security client components

The following table lists the network ports and protocols that are used for communications between Client Security servers and client computers. Depending on the type of firewalls you use and the location of those firewalls, you may need to open these ports.

noteNote:
These ports do not include the ports used for Group Policy, Domain Name System (DNS), and other standard technologies. For a list of ports used by Microsoft server products, see Network Ports Used by Key Microsoft Server Products (http://go.microsoft.com/fwlink/?LinkId=86643).
