My environment has four secure networks that branch off the main network. I have two gateway servers in each secure network to handle authentication for their agents and their network devices to communicate back to the main network which hosts my OpsMgr management group (OM 2012 sp1). For all intents and purposes each secure network is isolated from the others and only have a limited connection to the main network.
Question 1: Should I create a resource group for each set of gateways or one gateway resource group for all of them?
Question 2: In each secure network should I use both of the gateway servers to handle both network and agent communication or should I setup one gateway for network and the other for agents?
