Connect Remote Sites using GUP

Hello,

I was looking for a solution to connect RemoteClients to my SEPM. I know from McAfee that I can use an Agenthandler to connect a different subnet and the clients communicate to the management server using this agent handler.

My first understanding of a GUP was that I can realize it the same way. At least for updating the policies and virus definitions.

In the picture you can see, what I want to realize. The GUP should work as a connection between two networks. The SEP Clients only have connection to the GUP, but not the the SEPM.

I already configured one client to work as gup but I cannot connect the other SEP clients. First I need to know if its generally possible?

Thanks
