How to Turn Off the Firewall to Play Online Multiplayer Gamesby C. Taylor
Online multi-player games require an Internet connection to communicate with central servers. However, Windows 8's firewall automatically blocks programs it considers high-risk, which could include your game. Turning off the Windows firewall will let you play the game, but this step potentially exposes your computer to unauthorized access. Another option is to allow the program through the firewall. Doing so not only allows you to play the online game but it also maintains protection from online threats.
Disabling Windows Firewall
Type “Firewall” at the Windows 8 Start screen, click “Settings” and select “Windows Firewall” from the search results.
Click “Turn Windows Firewall On or Off” from the left panel.
Click “Turn Off Windows Firewall (Not Recommended)” in the Private Network Settings section and click “OK.”
Try the game. If it works, you don’t need to continue. If it still doesn’t work, repeat the procedure, but also click “Turn Off Windows Firewall (Not Recommended)” in the Public Network Settings section.
Creating an Exception
Type “Firewall” at the Windows 8 Start screen, click “Settings” and select “Allow an App through Windows Firewall” from the search results.
Click “Change Settings” from the Allowed Applications window.
Check the box to the left of your listed game to enable the exception. If you can’t find your program, click “Allow Another App” and double-click the game in the "Add an App" list.
Check both boxes to the right of your game to enable the program to communicate through public or private networks.
