The following ports must be opened in order to use MATLAB Parallel Server with Online Licensing on Amazon EC2.
TCP Ports - Usage
  • 443 - Web access to Cloud Center
  • 22 - SSH
  • 27355 - Access to MATLAB job scheduler on head node
  • 14350–14415 - MATLAB pool or parallel pool workers (R2012b and later)
  • 40000–40065 - MATLAB pool workers (R2012a)
In addition to the above ports the following domains will need to be allowed/bypassed.
  • login.mathworks.com
  • services.mathworks.com
  • licensing.mathworks.com
NOTE: Starting in R2019a the following name changes occurred:
  • MATLAB Distributed Computing Server was renamed to MATLAB Parallel Server
