Port Isolation is used to limit data transmission between ports. In Port Isolation, you can define a Forwarding Port List for each port. And the port can send data only to the ports in the list. Packets sent to the other ports will be dropped.
Here is an application example for Port Isolation. Host A, B, C are connected to port 1, 2 and 3 respectively. Server A and server B are connected to port 4 and port 5 respectively. It is required that Host A, B and C cannot communicate with each other; Host A can visit both server A and server B, while host B and host C can only visit server A.
Configuration Scheme:
To meet the requirement, you can define different Forwarding Port List for each port. Note that since communications are bidirectional, if you want two ports communicate normally, they need to be in each other’s forwarding lists.
