Azure, Hypher-V machine getting out to the internet

Hello there,

I would like to ask a question:

In Azure, I have created a Virtual Machine with Windows 2016.

This machine has connectivity to the internet ( 10.0.0.4 , gateway 10.0.0.1 , and DNS itselft (10.0.0.4) because it is a Domain Controler )

In that Virtual Machine I have installed the Hyper-V feature.

Inside Hyper-V I have created a Virtual machine.

This virtual machine is domain-joined ( 10.0.0.5 , Gateway: 10.0.0.1 , DNS: 10.0.0.4 )

This virtual machine is attached to a Hyper-V virtual switch set as external. In that scenario, why does the virtual machine inside Hyper-V cannot reach 8.8.8.8 through ping ?

I tried to set "IP Forwarding" to the network nic attached to the Hypher-V host , so that the machine inside Hyper-V could get to the internet, but it hasn't worked.

I don't get much information throught "tracert 8.8.8.8" , all it says is "not reachable" but it doesn't even reach 10.0.0.1 , maybe because that IP is Azure-managed ( the gateway )

Any thoughts on this?  , thanks in advance!
