Functions

func Apoxy4To6Range

func Apoxy4To6Range() netip.Prefix

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

func NewApoxy4To6Prefix

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

NewApoxy4To6Prefix generates a new IPv6 address from the Apoxy4To6Range prefix.

func TrySTUN

func TrySTUN(srcPort int, addrs ...string) (net.IP, []int, error)

TrySTUN tries to resolve the external IP address and port of the host by sending a STUN request to the specified STUN servers.

Types
