    Hi there,

    in our company, the SfB Web App is installed on each client. But when a user joins a meeting the first time, SfB Web App always asks for creating firewall rules in Windows. Since most of the users don't have administrator privileges they click on "Cancel" and everything works fine. This is also the way Microsoft recommends for the users ( support.office.com/en-us/article/trouble-installing-the-skype-for-business-web-app-plug-in-958fc5f1-2d6f-42e3-815d-a9516c591274 ).

    Now we'd like to deploy the local firewall rules sitewide and we wonder if we have any benefits if we set them to "Allow" instad of the default "Block". They are application-based for a executable called "pluginhost.exe".

    Does anyone know which is the better state?

    Thanks and best regards

    Hello Thenicnic,

    It would be better to "Allow" the application through firewall.

    As you said, even if the user cancels the prompt they still can join the meeting and everything is working fine, but the "Allow" firewall rule helps in optimization and quality.

    This is what Microsoft is saying on the firewall prompt:

    Users may see a firewall warning the first time they run the meetings app. They may be prompted to open ports to optimize the experience, and this may require Admin privileges on the machine they may not have. The app should still function and the user can safely decline to open the requested ports.

    Hope this helps !
