Hi, This question was asked many times but still I have some confusion even though I followed MS articles for port. Could you please let me know all client ports towards Lync server with direction. I opened port TCP/UDP 1024 - 65535, 5061, 443, 8057, 5062,
5062. 5063 from Lync client towards Lync FE servers (unidirectional). I am unable to login. Is there any port required bi-directional? I already referred to all articles and none is telling the direction of port opening. My FW team needs a valid reason to
open ports bi-directional. Any help is appreciated. Thanks.
