  Hi Luis,

  The RD Licensing port requirements haven't changed in many years.  Please see document below:

  https://social.technet.microsoft.com/wiki/contents/articles/16164.rds-2012-which-ports-are-used-during-deployment.aspx#Remote_Desktop_Licensing_Server

  Are you experiencing an issue with your RDSH servers communicating with your RD Licensing server?

  Thanks.

  TP,

  Thank you for your quick reply. I'm not having any issues. I'm just trying to come up with the minimal port list between 2012r2 RDSH communicating with 2012r2 RD License server. Based on the link you sent and a few others I read I'm thinking this is the minimal list needed for Per User CAL issuing:

  • TCP 135
  • TCP 139
  • TCP 445
  • UDP 137-138
  • TCP 49152 - 65535

  Do you agree? I assume the connection is always initiated by the RDSH Or is there a case for the License Server initiating connection to the RDSH?

  Thanks,
  Luis

  Hi,

  Not based on my understanding (considering RDS roles only).

  Best Regards,

  Hi Luis,

  RDSH/RDVH contacts RD Licensing server during user connection when needed.  RD Licensing server contacts Clearinghouse in some cases, for example, when Activating/Re-Activating, installing/migrating licenses, etc.
