Port Requirements


Topic Last Modified: 2012-11-16

Microsoft Lync Server 2010 requires that specific ports on the firewall be open. Additionally, if Internet Protocol security (IPsec) is deployed in your organization, IPsec must be disabled over the range of ports used for the delivery of audio, video, and panorama video.

For details about ports for Edge Servers and external firewalls, see Topologies for External User Access in the Planning documentation.
