NatVppAPI provides methods for managing VPP NAT configuration.

func CompatibleNatVppHandler

func CompatibleNatVppHandler(
	ch govppapi.Channel, ifIdx ifaceidx.IfaceMetadataIndex, dhcpIdx idxmap.NamedMapping, log logging.Logger,
) NatVppAPI

type NatVppRead

type NatVppRead interface {
	// Nat44GlobalConfigDump dumps global NAT44 config in NB format.
	Nat44GlobalConfigDump() (*nat.Nat44Global, error)
	// DNat44Dump dumps all configured DNAT-44 configurations ordered by label.

}

NatVppRead provides read methods for VPP NAT configuration.
