Routing between two subnets

Hi, I've created two subnets on the same virtual network.
I've defined a default route to a Azure firewall in this vnet.
I can reach two sample hosts (one on each subnet) with RDP from internet, passing through the firewall.
But If I try to produce traffic from a host to the other and vice versa, this traffic doesn't go to firewall.
How to solve?

    "Hub&Spoke" is the name of a network topology, nothing "Azure-Special":

    Hub-spoke network topology in Azure

    Without knowing your detailed requirements or targets it's hard to say.

    A subnet A, a subnet B, all subnets must do traffic to and from internet through a virtual firwall, each subnet must be separated from the other and the firewall must manage also this traffic with policies.
    How to do that?

    Sounds like a Hub and Spoke topology is a good option:
    Hub virtual network with the firewall and 2 spoke virtual networks with the VMs.
