The customer LAN connection for the SMWeb CMICs can be protected with an external hardware firewall. This firewall limits the traffic between the CMIC and the client boxes for the customer’s LAN to only those defined ports necessary for operation.
The following table documents which ports and protocols must be opened across the firewall to allow the Java Client to function.
Each active remote session, for example on the Java Client, a client box must have a port in the range 7744-7763 open and accessible for callback from the server.
|7744 to 7763||RMI/SSL/TCP||Server||Exported Remote Interfaces|
|7757||RMI/SSL/TCP||Client||RMI Registry Service|
|7758 to 7759||RMI/SSL/TCP||Client||Connection Tunnel Service|
|9981||HTTPS||Client||CMIC Web/REST Services|
