These all are IETF standards protocols and hence Microsoft also uses them. Since these are the most commonly used RFC standard protocols SFB clients also use them.
So now we can understand clearly that the External Corporate firewall requires a Hairpin traffic to be allowed for the A/V edge Public IPs for the STUN and TURN to work in the required UDP TCP path. Once this chain is established it promises the remote client to send its media connection to the internal network client. By using this, edge servers will create a chain and will offer ports on UDP and TCP for the This will establish a chain of connection between the external client and the client inside the network. TURN: Traversal Using Relay around NAT.This will allow the SFB client to discover the available public IP for the SFB media path in order to establish the connectivity. STUN: The new name for this acronym is Session Traversal Utilities for NAT.Protocol which functions as the core and wraps the other two to establish a path. All Lync/SFB clients are ICE clients and use ICE to try and establish connectivity between itself and another ICE client. ICE: The stands for Interactive Connectivity Establishment protocol for communications.SFB/Lync uses all these 3 protocols to establish a media connectivity: So started to explore on STUN, TURN & ICE since was having a glossy look on these topics. This is the time to dig into the analysis of which protocol fashion the SFB clients establishes the connection. Getting error as call failed due to media connectivity failure when both the end points are remote. No edge hair pin traffic is allowed for Audio and Video Public IPs.ĭid a Snooper trace from the affected remote client and got the following info on the snooper logs.Port 50000 was blocked in my case since no legacy OCS clients.The edges were in DNSLB and were in scaled consolidated topology using NAT.Did a telnet to on port 443 – successful.(This was done just to make sure the clients when logging in gets all the updated info of the pool, SFB config etc.) from remote users n/w to my office n/w – received error (we couldn’t connect to the presentation because of n/w issues.
from remote users n/w to my home n/w – received error (we couldn’t connect to the presentation because of n/w issues.Step 7: If you are still having issues after performing all the steps here, please contact us! We will be happy to help as soon as possible.
