If you are looking to configure S2S between multiple branches so that they can connect to each other then you should deploy S2S multi-site configuration setup.
This config looks after the single connect VPN that connects the multiple corporate locations with each other. Make sure that the virtual network gateway for your VNet is RouteBased.
Here is the list off compatible VPN devices to configure. See About VPN Devices.
If you don’t see your device listed in the Validated VPN devices table, your device still may work with an Azure Site-to-Site connection. You may contact your device manufacturer (NetGear) for additional support and configuration instructions.
