Step 2: Create a New Rule

Create a new rule or edit an existing one.

Step 3: Define the Rule

In the rule settings, specify the IP address to be whitelisted in the source field, set the action to allow, and define any additional parameters as required.

Step 4: Add New IP Addresses

To add new IP address, click on + icon under sources. In the services field, you can click on the + icon to specify a specific port for that address.
