Up and Ready describes how to solve port conflicts after starting to use Autodesk Network License Manager 11.12 and for ArcGIS, you also need to use the 32 bit version of the Autodesk Network License Manager.
“For example, when configuring Autodesk licensing service with Foundry, ArcGIS or CamWorks, you will need to edit our license files to use a differnet port for lmgrd.exe. i.e. 27000 (default) to 27001”
“if you are using Autodesk and Abaqus software in your company, you will need to even customize the adskflex.exe port (2080) in our license file”
