Issue:

How to set exceptions for Autodesk Network License Manager in Windows Firewall.

Solution:

Autodesk Network License Server uses the first available TCP port in 27000 to 27009 range for lmgrd (the master daemon) and TCP port 2080, which is reserved port for adskflex (Autodesk vendor daemon).  Thus after installing the Downloading the Network License Manager - Network Admin Autodesk Network License Manager, network communication through these ports must be open in order to have a functional network license manager.

1. Open Windows Firewall (Control Panel\System and Security\Windows Firewall) – Advanced settings

2. Select – Inbound Rules

  1. New Rules
  2. Port – Next
  3. TCP – and type 2080, 27000-27009 in specific port box > Next    
  4. Select Allow the connection > Next
  5. Select Domain, Private, Public
  6. Name – Autodesk lmgrd (or one of your choices)

3. Select – Outbound Rules

  1. New Rules
  2. Port – Next
  3. TCP – and type 2080, 27000-27009 in specific port box > Next     
  4. Select Allow the connection > Next
  5. Select Domain, Private, Public
  6. Name – Autodesk lmgrd (or one of your choice)

Attention:
Please set in all rules the Client ports to All ports and the Server ports to  2080, 27000-27009, as the license tool on the client will use also other ports.
The server will always use by Default the ports 2080, 27000-27009 unless you change the ports in the license file.
