If you want to allow that program to communicate through the firewall, you can usually do that by selecting the program on the
Exceptions tab in Windows Firewall. By default, most programs are blocked by Windows Firewall, to help make your computer more secure. To work properly, some programs might require you to allow them to communicate through the firewall. Here's how to do that:
- Open Windows Firewall by clicking the Start button ? Control Panel ? Security ? Windows Firewall.
- In the left pane, click Allow a program through Windows Firewall. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
- Select the check box next to Tennis Elbow 2011, and then click OK.
However, if
Tennis Elbow 2011 isn't listed on this, you might need to open a port (default 4321). You might need to add this port for the game so that the firewall allows the game information to reach your computer. Unlike an exception, which is only open during the time that it is needed, a port stays open all the time, so be sure to close ports that you don't need anymore.
- Open Windows Firewall by clicking the Start button ? Control Panel ? Security ? Windows Firewall.
- Click Allow a program through Windows Firewall. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
- Click Add port.
- In the Name box, type a name that will help you remember what the port is used for.
- In the Port number box, type the port number (default 4321).
- Click TCP or UDP, depending on the protocol.
- To change scope for the port, click Change scope, and then click the option that you want to use. ("Scope" refers to the set of computers that can use this port opening.)
