Firewall settings
To allow clients to connect to the license manager,
incoming TCP-traffic to the port that the server is listening on must be allowed.
The default port number used by the CLC Network License Manager is 6200. This can be
changed if desired, as described in TCP_LISTEN_PORT.
To allow use of the auto-discovery feature, incoming broadcast UDP traffic to port number 6200 must be allowed. This port number cannot be changed.
