Backup Endpoints via Cloud Gateway

Dear Veeam Community,

I hope you can enlighten me.
We have the goal to setup endpoint backups without the use of a vpn.
We installed veeam b&r & cloud gateway on a test server so far.
Now whe thought we could like generate an agent for a tenant and then install that agent to endpoints of this tenant to be able to backup files of the endpoint via the cloud gateway direkcly into the configured tenant backup repository.

At this point we’ve tried a lot and I doubt that this will work the way we intended.
It seems like the cloud gateway is used to connect different vbr servers and save their backups in a service providers repositories. 
But that wouldnt solve the problem that the customer needs an own vbr and a vpn to have a connection between his endpoints and his vbr server in order to back the endpoints up to the service provider. 
(Endpoint → Tenants VBR Server → Cloud Gateway → Service Providers Repositories)

Is there any chance to make it work like this:
Agent on Endpoint → Cloud Gateway → Veeam B&R of Service Provider / configured repository of  tenant?


Thanks in advance for any answer!
