Some of BitDefender's computer security software, such as BitDefender Total Security and BitDefender Internet Security, include firewall components. A software firewall is designed to shield your computer from unwanted access attempts over the Internet by preventing information that you do not request from getting to the computer. However, a firewall can also prevent your computer from receiving information that you do want it to receive. If this is the case, open the associated port in BitDefender's firewall to configure it.
