  1. Why do apps need access to communicate through firewalls?


    I recently downloaded Unity and it wants me to allow access through the firewall. I trust it and I allowed it through private networks but I don't understand why I need to do this. What does Unity need to have from my computer that my firewall blocks? And not just unity but also all apps. Take chrome for example, it wants access to communicate through private or public networks. What does this mean to begin with?

    :)

    Windows Firewall blocks App Store from downloading new apps

    Hi,

    Let's try to check if the app store you're referring to if it's really blocked by Windows Firewall. See these steps:

    • Open Windows Firewall from the taskbar >
      Firewall & network protection
      > Allow an app through firewall.
    • A new window will show up containing the list of the apps that ca be allowed through Firewall.
    • Look for the app you want to be accessed, and make sure that the Domain, Private and Public are ticked. That would allow the app store to be accessed.

    Let us know what happens after doing the suggestion.

    Restraint trafic and applications to access internet with Firewall when connected with Dial Up SAT connexion

    Hi,

    To address this concern, we suggest that you follow these steps on how to block apps and programs from accessing network connection through Windows Firewall:

    • Open Control Panel and click System and Security.
    • On the Windows Firewall page, select Allow a program through Windows Firewall.
    • Uncheck the box to the left of the application names to disallow them from accessing network connection.
    • If other programs are not listed, just click Allow another program/app button to add them.

    Let us know how it goes.

    Thank you.

    Windows Firewall - how to allow access

    I believe that my firewall is blocking access to Family Tree Maker / Ancestry / MacKiev SYNC - I can't see any reference to any of these names in the allowed list ....

    I can't see any way of adding to the allowed list

    Any suggestions ?
