Technical Details

what runs on :1542

The IANA assignment covers both TCP and UDP under the service name gridgen-elmd. A Gridgen license server may listen on this port for license-client communication; the public registry does not document a handshake, framing format, default negotiation behavior, or protocol relationship between the TCP and UDP endpoints.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

This is generally an internal license-service endpoint and should not be exposed directly to the public internet. Restrict it to authorized Gridgen clients and license administrators with firewall rules; because the protocol's authentication and encryption behavior is not documented here, treat traffic as potentially cleartext and avoid relying on the port alone for access control.
