General questions

Which IP version does Gatekeeper support?

Gatekeeper supports IPv4 and IPv6 networks.

Concepts

What defines a flow in Gatekeeper?

A flow is defined as the pair of source and destination IP addresses. All policy decisions are enforced over flows.

What are vantage points?

Vantage points (VPs) are locations that support the deployment of Gatekeeper servers. Besides the basic hardware demands, these locations must provide BGP speakers to announce protected network prefixes and private links between the VP and the protected destination. The private links are used to make Gatekeeper servers the entry points of traffic toward the protected destinations. These private links can be implemented using a number of technologies, including regular tunnels. Typical VPs are Internet exchanges, peer links, and (some) cloud providers; not all cloud providers support BGP announcements.
