Open/Close Port

This extension allows you to add or delete packet traffic management rules on the gateway, allowing any (or specific) host IP from a designated subnet to communicate with the gateway through specified ports.

Install the Open/Close Port Extension

To install the extension, follow the steps in Add an Extension section.

Configure the Open/Close Port Extension

1. To access the Open/Close Port extension, click Launch.

Figure 1: Launch the Open/Close Port Extension

After clicking Launch, the Traffic rules page will be displayed, showing the default rules of the Open/Close port extension with the following parameters:

• Service name: A readable name for the service.
• Protocol: The protocol used.
• Family: The protocol version used for the traffic.
• From: External source
• To: Internal source

Figure 1: Traffic rules page

For example, the Allow-http service indicates that any host in WAN can communicate with the gateway through port 80 using the TCP protocol type.

NOTE

Click ⋮ and select Delete to remove the traffic rule. After deletion, the UI may still appear accessible for a short time due to browser caching. Clear the browser cache or wait a few minutes for the firewall changes to take effect.

2. To add a new rule, click the Add new rule and configure the following information:

• Service name: Provide a readable name for the rule.
• Protocol: Select the protocol used for the rule:
  • TCP
  • UDP
  • TCP + UDP
• Sources:
  • Allow any host: Allows any host to access the rule.
  • Source IP address: Specify up to three host IPs.
• Destination port: The destination port for routing.
