Use this method if you want to see if Windows is set up to allow an app you've installed to communicate through your firewall. The Windows firewall is enabled by default. If you've installed your own firewall software, use that software to check if an app is allowed through. This opens your Firewall and Network Protection settings. It's one of the text links near the bottom of the window. A list of apps allowed through the firewall will appear.  If the app is allowed through the firewall only when you're connected to a network you've marked as "private" (such as when you're on your home network), a check will appear in the "Private" column next to the app. If the app is allowed through the firewall when you're connected to a public network, a check will appear in the "Public" column. If you don't see the app on the "Allowed apps and features" list, click the Change Settings button at the top-right corner, and then follow these steps:  Click Allow another app near the bottom. Click Browse, select the app, and then click Open. Click Network Types near the bottom-left corner, select a privacy preference, and then click OK. Click Add to add the app, and then click OK.
