Network settings
The network restrictions (such as firewalls and routers) should support the Lync policy settings:
- If the valueClientMediaPortRangeEnabledis false, each port range value should be open for communication between theNDSmachine and the end users.
- If the valueClientMediaPortRangeEnabledis true, the port range specified by [ClientAudioPort , ClientAudioPortRange] should be open for communication between NDS machine and the end users.
Normally, the network settings support the Lync requirements. However, if you need to open more ports, you might need to make network changes.
