Config is a complete tunnel configuration

func Load

func Load(r io.Reader) (*Config, error)

Load loads and parses an io.Reader as a tunnel config, returning a Config pointer or an error.

func (*Config) FeatureFlags

func (c *Config) FeatureFlags() uint32

FeatureFlags returns the set of features required to handle a tunnel configuration.

func (*Config) Remap

func (c *Config) Remap()

Remap changes all forwarding directives to use the default localhost address 127.0.0.1 instead of their configured source, if it differs from 127.0.0.1.

func (*Config) SourceAddresses

func (c *Config) SourceAddresses() []string

SourceAddresses returns all the source addresses used in forwarding directives.

type Forward

type Forward struct {
	Name     string

type ForwardLine struct {
	Src Addrports
	Dst Addrports
}

ForwardLine is a specific port or range or ports to forward

func (ForwardLine) DstString

func (line ForwardLine) DstString(i int) string

DstString returns the destination IP address and port as a string formatted for use with Dial() and similar.

func (ForwardLine) SrcString

func (line ForwardLine) SrcString(i int) string

SrcString returns the source IP address and port as a string formatted for use with Dial() and similar.

func (ForwardLine) String

func (line ForwardLine) String() string

String returns a human readable representation of the port forward.
