Port summary - Single Director in Lync Server 2013

 

Topic Last Modified: 2012-10-20

Firewall port requirements for a single Director consist of the ports that are used to establish communication with the Director from the internal interface or internal-facing network of the reverse proxy. Microsoft Lync Server 2013 by default expects ports HTTP/TCP 8080 and HTTPS/TCP 4443 to be open from the reverse proxy to the Director, as well as the Front End pool and Front End Server. Additionally, there must be session initiation protocol (SIP) communication from the Edge Server internal interface to the Director and to the Front End pool and Front End Server. The SIP protocol uses SIP/MTLS/TCP 5061 from the Edge Server to the Front End pool and Front End Server. A rule that allows SIP/MTLS/TCP 5061 communication from the Director, Front End pool and Front End Server to the Edge Server internal interface must be created as well.
