How to add ports for avira
You can configure a firewall to allow user-defined traffic. (firewall image by dinostock from

Avira Premium Internet Security contains a firewall program that blocks unwanted or dangerous Internet traffic from your computer. The firewall has default settings to allow safe traffic to pass to your computer, e.g., Hypertext Transfer Protocol (HTTP) on port 80 or File Transfer Protocol (FTP) on port 21, but blocks unknown or unauthorised ports. You can add a firewall rule to configure Avira to allow open ports for applications that are not covered by the default settings.

Skill level:


  1. 1

    Click the Windows "Start" menu, click "All Programs" and scroll to "Avira." Click the icon and select "Start AntiVar." You can also right-click the Avira icon in the system tray and select "Start AntiVar."

  2. 2

    Click the "Online Protection" tab and select "Firewall." Above the list of applications that the firewall is monitoring, click "Configuration."

  3. 3

    Double-click "Firewall" from the menu on the left and click "Adapter Rules." Highlight "Incoming Rules" and click "Add Rule." Follow the prompt to give the new firewall rule a name. For easy identification use the name of the application or the port number you are allowing, for example "Bouncing Bubbles Game" or "Port 105." Select "Incoming TCP Rule" and click "OK."

  4. 4

    Click "<empty>" in the new firewall rule displayed under the list of existing rules. Follow the prompt to enter a port or range of ports to open for incoming traffic. To open more than one port under a single rule, separate the port numbers with a comma. For example, "23, 106, 155." Open a range of ports using a format such as "50-125." Click "Apply" to save the new rule.

  5. 5

    Click "Outgoing Rules" to create a new rule for outgoing traffic. Click "Add Rule," name the rule and select "Outgoing TCP Rule." Click "<empty>" in the new firewall rule and enter a port or range of ports to open for outgoing traffic. Click "Apply" to save the new rule.

Tips and warnings

  • Avoid opening unnecessary ports that can be used to exploit your system. If you no longer use an application that requires a custom port to be open, delete the firewall rule to close the port.
