Types

type Config

type Config struct {
	Server  string
	Verbose bool
	Local   string
	Net     *vnet.Net
}

Config has config parameters for NewNATS.

type DiscoverResult

type DiscoverResult struct {
	IsNatted          bool                   `json:"isNatted"`
	MappingBehavior   EndpointDependencyType `json:"mappingBehavior"`
	FilteringBehavior EndpointDependencyType `json:"filteringBehavior"`
	PortPreservation  bool                   `json:"portPreservation"`
	NATType           string                 `json:"natType"`
	ExternalIP        string                 `json:"externalIP"`
	ExternalPort      string                 `json:"externalPort"`
}

DiscoverResult contains a set of results from Discover method.

type EndpointDependencyType

type EndpointDependencyType uint8

EndpointDependencyType ...

const (
	// EndpointIndependent means the behavior is independent of the endpoint's address or port
	EndpointIndependent EndpointDependencyType = iota
	// EndpointAddrDependent means the behavior is dependent on the endpoint's address
	EndpointAddrDependent
	// EndpointAddrPortDependent means the behavior is dependent on the endpoint's address and port
	EndpointAddrPortDependent
	// EndpointUndefined ...
	EndpointUndefined
)

func (EndpointDependencyType) String
