hyper-v network virtualization gateway

Hi

I am planning a small testlab for Hyper-V network virtualization and SCVMM 2012 SP1. Now I am confused about the virtualization gateway. My understanding is that when the VMs needs external connection (Internet, other physical host etc.) then I need a virtualization gateway. Right?

So, is it possible to configure a Hyper-V Host itself or a VM as a virtualization gateway for a testlab?

Moreover, when you configure a virtualization Gateway with Windows Server 2012 can you manage it through SCVMM 2012 SP1or do you need maintain it manually?

Thx
