Types

type LocalTrafficDetector

type LocalTrafficDetector interface {
	// IsImplemented returns true if the implementation does something, false otherwise
	IsImplemented() bool

	// JumpIfLocal appends conditions to jump to a target chain if traffic detected to be
	// of local origin
	JumpIfLocal(args []string, toChain string) []string

	// JumpINotfLocal appends conditions to jump to a target chain if traffic detected not to be
	// of local origin
	JumpIfNotLocal(args []string, toChain string) []string
}

LocalTrafficDetector in a interface to take action (jump) based on whether traffic originated locally at the node or not

func NewDetectLocalByCIDR

func NewDetectLocalByCIDR(cidr string, ipt utiliptables.Interface) (LocalTrafficDetector, error)

NewDetectLocalByCIDR implements the LocalTrafficDetector interface using a CIDR. This can be used when a single CIDR range can be used to capture the notion of local traffic.

func NewNoOpLocalDetector

func NewNoOpLocalDetector() LocalTrafficDetector

NewNoOpLocalDetector is a no-op implementation of LocalTrafficDetector
