Port summary - Single consolidated edge with public IP addresses in Lync Server 2013

Lync Server 2013
 

Topic Last Modified: 2013-02-21

The Lync Server 2013, Edge Server functionality described in this scenario architecture is very similar to what was implemented in Lync Server 2010. The most noticeable addition is the port 5269 over TCP entry for the extensible messaging and presence protocol (XMPP). Lync Server 2013 optionally deploys an XMPP proxy on the Edge Server or Edge pool and the XMPP gateway server on the Front End Server or Front End pool. Planning information for the reverse proxy and federation are found in Scenarios for reverse proxy in Lync Server 2013 and Planning for SIP, XMPP federation, and public instant messaging in Lync Server 2013 sections, respectively.

In addition to IPv4, the Edge Server now supports IPv6. For clarity, only IPv4 is used in the scenarios.

We recommend that you open only the ports required to support the functionality for which you are providing external access.

For remote access to work for any edge service, it is mandatory that SIP traffic is allowed to flow bidirectionally as shown in the Inbound/Outbound edge traffic figure. Stated another way, the SIP messaging to and from the Access Edge service is involved in instant messaging (IM), presence, web conferencing, audio/video (A/V) and federation.
