Internet Shield Firewall

Q14. How can I open a port through the firewall?

You can open a port through the firewall if you want to allow some Internet traffic and you know the port number that you want to open.

You may not be able to add your own rules to all security levels. Select the security level to which you want to add the new rule before you open the port.

When you open a port through the firewall, you create a new firewall rule and two new services.

1. Click the Internet Shield tab.
2. Click Open a port.
3. In the Name field, enter a name for the new firewall rule.
4. In the Port number field, define the responder port for the rule. The responder port is usually mentioned in the product documentation.
5. Click OK.

The new rule is added to the firewall rules list and two new services are created on the firewall services list for both the TCP and UDP protocols with the specified port number.
