Hello,

I recently added some URL rules to our firewall but they are allowing access to our entire FDQN, which I don't want.

Users are being able to browse all of our www.au.edu. I see in the firewall logs that this is being allowed by that URL rule.

How can I stop this behavior or am I misconfiguring something?

    Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

    I understand that you would like to block all access to https://www.au.edu/ using Azure Firewall for all users.

    You can add a ApplicationRule in the FIrewall or the Firewall Policy such as below.

    This should restrict access to *.au.edu
