Protected Ports

Scenario

Protected Port is a security feature that prevents hosts connected under protected ports to communicate with each other. This allows for a simple traffic policy that isolates communications between end stations while the path to the Internet is uninterrupted.

* Hosts connected under a port with Protected Port enabled, CAN communicate with Hosts connected under a port with Protected Port disabled. Isolation only occurs when both ports under both hosts have Protected Ports enabled.

Under the following topology:

 

- Host-A can ping Gateway.

- Host-B can ping Gateway.

- Host-A cannot ping Host-B.

Step

1.  Access the GS1900-24 through Web GUI.

2. Go to CONFIGURATION > Security > Protected Port.

3. Enable Protected Port for Port 2 and Port 3.

4. Ensure that Port 1 has Protected Port disabled.

5. Connect a Gateway with IP address 192.168.1.1 to port 1 of the GS1900-24.

6. Connect a PC using IP address 192.168.1.2 to port 2 of the GS1900-24.

7. Connect another PC using IP address 192.168.1.3 to port 3 of the GS1900-24.

 

 

Verification

1. Have Host-A ping  IP address 192.168.1.1.

2. Ping should be successful.

3. Have Host-A ping IP address 192.168.1.3.

4. Ping should NOT be successful.
