Types

type Config

type Config struct {
	WgListenAddr string
	RemoteKey    string
	WgInterface  *iface.WGIface
	AllowedIps   string
	PreSharedKey *wgtypes.Key
}

type DirectNoProxy

type DirectNoProxy struct {

	// RemoteWgListenPort is a WireGuard port of a remote peer.
	// It is used instead of the hardcoded 51820 port.
	RemoteWgListenPort int
	// contains filtered or unexported fields
}

DirectNoProxy is used when there is no need for a proxy between ICE and WireGuard. This is possible in either of these cases: - peers are in the same local network - one of the peers has a public static IP (host) DirectNoProxy will just update remote peer with a remote host and fixed WireGuard port (r.g. 51820). In order DirectNoProxy to work, WireGuard port has to be fixed for the time being.

func NewDirectNoProxy

func NewDirectNoProxy(config Config, remoteWgPort int) *DirectNoProxy

NewDirectNoProxy creates a new DirectNoProxy with a provided config and remote peer's WireGuard listen port

func (*DirectNoProxy) Close

func (p *DirectNoProxy) Close() error

Close removes peer from the WireGuard interface

func (*DirectNoProxy) Start

func (p *DirectNoProxy) Start(remoteConn net.Conn) error

Start just updates WireGuard peer with the remote IP and default WireGuard port

func (*DirectNoProxy) Type

func (p *DirectNoProxy) Type() Type

Type returns the type of this proxy

type DummyProxy

type DummyProxy struct {
	// contains filtered or unexported fields
}

DummyProxy just sends pings to the RemoteKey peer and reads responses

func NewDummyProxy

func NewDummyProxy(remote string) *DummyProxy

func (*DummyProxy) Close

func (p *DummyProxy) Close() error

func (*DummyProxy) Start

func (p *DummyProxy) Start(remoteConn net.Conn) error

func (*DummyProxy) Type

func (p *DummyProxy) Type() Type

type NoProxy

type NoProxy struct {
	// contains filtered or unexported fields
}

NoProxy is used just to configure WireGuard without any local proxy in between. Used when the WireGuard interface is userspace and uses bind.ICEBind

func NewNoProxy

func NewNoProxy(config Config) *NoProxy

NewNoProxy creates a new NoProxy with a provided config

func (*NoProxy) Close

func (p *NoProxy) Close() error

Close removes peer from the WireGuard interface

func (*NoProxy) Start

func (p *NoProxy) Start(remoteConn net.Conn) error

Start just updates WireGuard peer with the remote address

func (*NoProxy) Type

func (p *NoProxy) Type() Type

type Proxy

type Proxy interface {
	io.Closer
	// Start creates a local remoteConn and starts proxying data from/to remoteConn
	Start(remoteConn net.Conn) error
	Type() Type
}

type Type

type Type string

const (
	TypeDirectNoProxy Type = "DirectNoProxy"
	TypeWireGuard     Type = "WireGuard"
	TypeDummy         Type = "Dummy"
	TypeNoProxy       Type = "NoProxy"
)

type WireGuardProxy

type WireGuardProxy struct {
	// contains filtered or unexported fields
}

WireGuardProxy proxies

func NewWireGuardProxy

func NewWireGuardProxy(config Config) *WireGuardProxy

func (*WireGuardProxy) Close

func (p *WireGuardProxy) Close() error

func (*WireGuardProxy) Start

func (p *WireGuardProxy) Start(remoteConn net.Conn) error
