Inbound per IP Rate Limit Discarded IPv6 IPsec Unauthenticated Packets per Second is the rate at which unauthenticated IKEv1, IKEv2, AuthIP, or ESP IPv6 packets are received on a public interface and discarded because they exceeded the per internal IP address rate limit for IPv6 IPsec unauthenticated packets. An unauthenticated packet is an IPsec packet without an associated state entry. A state entry is a pair of IPv6 addresses that is authorized to pass through from a public to an internal interface.
