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
