Firewall rule CS TCP 13457 used for??? RRS feed

  • Question

  • I am trying to lock down our firewalls and see lync created a rule "CS TCP13457" on all of them. I cant find anything that says what this port is used for. Anybody else have this rule and do you know what is used for?

     

    Thanks,

    Jamali

  • That port is used by Lync to set the Kerberos password (Set-CsKerberosAccountPassword) on the web services for Front End and Director servers, if Kerberos authentication has been configured in your environment.

    It is my understanding that TechNet documentation will be updated to include this missing information in the near future.

  • Now I am curious why you would need that port if you are not using customized ports?
    I have not seen this port anywhere, can you explain?
