Functions

func CheckIfRestrictedNAT

func CheckIfRestrictedNAT(server string) (bool, error)

Deprecated: Use CheckIfRestrictedNATWithProxy Instead.

func CheckIfRestrictedNATWithProxy

func CheckIfRestrictedNATWithProxy(server string, proxy *url.URL) (bool, error)

CheckIfRestrictedNATWithProxy checks the NAT mapping and filtering behaviour and returns true if the NAT is restrictive (address-dependent mapping and/or port-dependent filtering) and false if the NAT is unrestrictive (meaning it will work with most other NATs),

Types

type StunServerConn

type StunServerConn struct {
	PrimaryAddr *net.UDPAddr
	OtherAddr   *net.UDPAddr
	// contains filtered or unexported fields
}

func (*StunServerConn) AddOtherAddr

func (c *StunServerConn) AddOtherAddr(addrStr string) error

func (*StunServerConn) Close

func (c *StunServerConn) Close()

func (*StunServerConn) RoundTrip

func (c *StunServerConn) RoundTrip(msg *stun.Message, addr net.Addr) (*stun.Message, error)
