Functions

func Apoxy4To6Range

func Apoxy4To6Range() netip.Prefix

Apoxy4To6Range returns the Unique Local Adddres prefix used by Apoxy for IPv4 to IPv6 translation.

func CreateKernelTunnel

func CreateKernelTunnel(
	addr netip.Prefix,
	bind conn.Bind,
	verbose bool,
) (*kernelTunnel, error)

CreateKernelTunnel creates a new kernel tunnel interface (TUN).

func CreateUserspaceTunnel

func CreateUserspaceTunnel(
	ctx context.Context,
	addr netip.Addr,
	bind conn.Bind,
	socksPort uint16,
	packetCapturePath string,
	verbose bool,
) (*userspaceTunnel, error)

CreateUserspaceTunnel creates a new user-space WireGuard tunnel.

func NewApoxy4To6Prefix

func NewApoxy4To6Prefix(orgID uuid.UUID, endpoint string) netip.Prefix

NewApoxy4To6Prefix generates a new IPv6 address from the Apoxy4To6Range prefix.

Types

type Tunnel

type Tunnel interface {
	io.Closer
	// Peers returns the public keys of the peers in the tunnel.
	Peers() ([]wireguard.PeerConfig, error)
	// AddPeer adds a new peer to the tunnel.
	AddPeer(peerConf *wireguard.PeerConfig) error
	// RemovePeer removes a peer from the tunnel.
	RemovePeer(publicKey string) error
	// PublicKey returns the public key of this end of the tunnel.
	PublicKey() string
	// InternalAddress returns the internal address of this end of the tunnel.
	InternalAddress() netip.Prefix
	// ListenPort returns the local listen port of this end of the tunnel.
	ListenPort() (uint16, error)
}

Tunnel is a WireGuard tunnel.
