Using Firewall

You can configure the firewall by creating and editing firewall rules. Firewall rules are a set of firewall services - Internet traffic parameters that control which type of traffic is allowed and denied. One rule can contain multiple services.

When you configure the firewall, you should allow only services that you need and deny all the rest Internet traffic to minimize security risks.

To configure firewall rules, follow these instructions:

  1. Click the Advanced link on the Internet Shield page. The Internet Shield Advanced Settings window opens.
  2. Select the security level you want to customize from the Internet Shield security level pull-down menu.
  3. Go to the Internet Shield Firewall Rules page.
  4. All rules belonging to the selected Security Level are displayed in the list. Do one of the following:
    • To change an existing rule, select the rule from the list and click Properties. For more information, see Creating A New Rule.
    • To change the order of the rules you have created yourself, right-click on the rule and select Move up or Move down in the pop-up menu. For more information, see Firewall Rule Order.
    • To add a new rule, click Add. For more information, see Creating A New Service and Creating A New Rule.
    • To delete a rule, select the rule from the list and click Delete.
      It is not possible to change or delete preset rules. You can only add new rules, or change and delete rules that you have added yourself.
