Hi @MaNolli

when you turn off (deallocate) the azure firewall, your vms will be without internet access (input or output). Set the Firewall to start approximately 20 minutes before your vms, as that's the time it takes to provision the environment

there is a powershell to deallocate and allocate:

I wrote a article in portugues to do that with runbook you can schedule:

You can translate with bing or google
