Hello anonymous usertuardo-5606 ,
Forced tunneling is supported on P2S VPN via custom routes and that forces all traffic from the client to Azure. You can direct all traffic to the VPN tunnel by advertising 0.0.0.0/1 and 128.0.0.0/1 as custom routes to the clients.

Note : Internet connectivity is not provided through the VPN gateway. As a result, all traffic bound for the Internet is dropped.
Kindly let us know if the above helps or you need further assistance on this issue.
