Creating A New Rule

When you have a service, you can add it to the firewall by creating a new rule.

To create a new rule to be used in the firewall, follow these instructions:

Step 1 - Rule Type
  1. Enter a name for the rule.
  2. Choose whether the rule either allows or denies the service.
  3. If you want to create a rule that is effective only when you have an active dial-up connection, select the Use this rule only with dial-up connection check box.
Step 2 - Specify Affected Hosts

You can apply the rule to all network connections or specify hosts and networks where the new rule applies.

  1. To apply the rule to all connections, check the Any IP Address check box and click Next to continue to choose the service.
  2. To specify hosts and networks where the rule applies, Clear the Any IP Address check box and click Edit.

  3. In the Add Host Address dialog, enter the details about the target addresses.
  4. Addresses can be listed in any order and type and can be any DNS name, IP address, subnet (in bit net mask format) or IP address range. For example:

    DNS name:

    www.example.com

    IP address:

    192.168.5.16

    IP range:

    192.168.1.1-192.168.1.63

    Subnet:

    192.168.88.0/29

    Click Add to list to add your new target to the list of targets to which this rule applies.

  5. Click OK to return to the Internet Shield Rule wizard and click Next to continue.
Step 3 - Choose the Service and Direction for the Rule

A firewall rule consists of a set of firewall services. Select services for which you want the rule to apply.

  1. Select the check box for every service you want the rule to apply. You can select as many individual services as you want in this window.
    For ease of configuration and maintenance, a single rule should contain only one service.
  2. If you want the rule to apply to all services, select All IP traffic from the top of the list.

    If the service you need is not in the list, you have to create it first. For more information, see Creating A New Service.

  3. For every service you selected, choose the direction in which the rule applies. To change the direction, click the icon in the Direction column:
    Direction
    Explanation
    The service will be allowed / denied to/from your computer in both directions.
    The service will be allowed / denied if coming from the Internet to your computer.
    The service will be allowed / denied if going from your computer to the Internet.
  4. Click Next to continue.
Step 4 - Choose Logging and Reporting Options

Select whether you want to be informed when the rule allows or denies traffic.

You can add a descriptive alert text for alerts that are logged or displayed as pop-ups.

Click Next to continue.

Step 5 - Review and Accept the Rule

Review the new rule. If you need to make any changes to the rule, click Back through the rule.

If you are satisfied with your new rule, click Finish.

Your new rule is added to the top of the list in the active set of rules on the Firewall Rules page.
