LMTOOLs consists of two utilities that need the following ports opened:

• "lmgrd.exe" needs incoming TCP on ports 27000-27009
• "lmtools.exe" needs TCP on port 2080

Standalone License activation happens on port 443 to "registeronce.autodesk.com"

For troubleshooting of LMTOOLs network licensing, we recommend using Wireshark which can be downloaded here.

Sample syntax for your capture filter:
(tcp.port==2080)||(tcp.port>=27000)||(tcp.port<=27010)
