     • Load Balancer service does not provide access control for Service IP and service ports.
       
       • When creating a Load Balancer, select Use Firewall to manage communication between the client and the Load Balancer, and between the Load Balancer and members with Firewall rules, and we recommend using Save Firewall Logs to store access logs.
     • When creating a service and enabling the Firewall log storage feature, you must configure the log storage first. If the log storage is not configured, you cannot create a Load Balancer service.
     Caution

     When using a firewall, you must add rules required for Load Balancer communication. Register the rules, paying attention to the direction for each purpose.
     

     • If you do not add a rule, the Load Balancer service will not operate correctly.

     

     Purpose	Source IP	Destination IP	Protocol	Destination Port/Type	direction
     Client → LB connection	Client IP	LB Service IP	Listener protocol	Listener service port	Outbound
     LB → Member connection	LB Source NAT IP	LB server group member IP	LB server group protocol	Member port	Inbound
     LB → Member health check	LB health check IP	LB server group member IP	Health check protocol	Health check port When the health check port and member port differ, register the member port	Inbound
