Issue:

Port numbers used by Autodesk Network License Manager for communication between clients and license server
 

Solution:

Autodesk Network License Manager needs the following TCP ports opened on the firewall - on the license server - so that client workstations are able to obtain a license from license server.

  • lmgrd.exe needs ports 27000 to 27009.
  • adskflex.exe needs port 2080.
These ports are used on server side. On the client side, other ports can also be used. So make sure that on client side all ports are open for the communication with license server.
