I have an EWC with 2 physical interfaces on esa0 because the customer is in transition to another owner and need to change the VLAN and IP structure globally. For that I need to configure the source IP for radius communication to the new physical interface IP. I cannot found the place to configure that. Further on the documentation is not clear that this will be part of the management traffic or not. If yes, what interface will be used when more than one interface will be configured for managment traffic ? Or is the interface used where the route to RADIUS server is configured ?
