I suspect the “Ethernet Trouble” is being caused by improper configured settings in ElkLink. Please reach out to your Installer to verify the IP Address for Central Station Surgard IP Receiver and the Port number as well as if DNIS is required. If the Central Station offers a Backup IP and Port that to should be verified. At this time the account appears to have a Backup IP BUT the Port is 0 which is not a valid port number.
