The License Manager components and the License Server rely on several Windows services, each of which requires correct firewall configuration to access the Internet and your network:
-
License Server Core Service
-
License Server Agent Service
License Manager uses the same ports as the two License Server Windows services, and must also be configured with access to the internet and to your network.
Depending on your particular environment, you may need to change the default port settings.
Caution! Be very careful when changing port settings. Doing so may impact product operation. The topics in this section detail how to go about changing the settings.
The following table lists the various ports.
