Creating A New Service

Before you can create a new rule to the firewall, you must have a service for the new rule. Service is most often described by what protocol and port it uses, for example web browsing uses TCP protocol and the port number 80.

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

  1. Click the Advanced link on the Internet Shield page. The Internet Shield Advanced Settings window opens.
  2. Go to the Internet Shield Firewall Services page.
  3. Click Add in the Firewall services page to open the Add new service dialog.
  4. Enter a name for the service in the Service description field.
  5. Select the protocol (TCP, UDP, ICMP) or define the protocol number for the service you want to specify from the Protocol drop-down list.
  6. If the service uses the TCP or UDP protocol, define the initiator and responder ports for the service.
    • To enter the ports and port ranges, click Edit beside the Initiator ports: and Responder ports: fields.
    • To add a single port, enter it in the Single: field and click Add To List.
    • To add a port range, add the lowest and the highest port of the range to the Range: fields and click Add To List.
  7. Click OK to add the ports and port ranges to the new service.
  8. Click OK to finish. You can now view the newly created service on the Firewall services page.
