Detailed Description

The CHANGE-REQUEST attribute contains two flags to control the IP address and port that the server uses to send the response.

These flags are called the "change IP" and "change port" flags. The CHANGE-REQUEST attribute is allowed only in Binding Requests. The "change IP" and "change port" flags are useful for determining the current filtering behavior of a NAT. They instruct the server to send the Binding Responses from the alternate source IP address and/or alternate port.

Constructor & Destructor Documentation

◆ AttributeChangeRequest()

NobleConnect.Stun.AttributeChangeRequest.AttributeChangeRequest	(	bool	changeIP,
		bool	changePort
	)

Construct an AttributeChangeRequest using the provided flags

This is called when constructing an Attribute to send to a Stun server.

Parameters

errorCode
errorMessage

Member Function Documentation

◆ GetValueSize()

override ushort NobleConnect.Stun.AttributeChangeRequest.GetValueSize ( )

virtual

Get the serialized size of the attribute values

Returns: Defined to be 4 bytes even though only 2 bits are ever used.

Reimplemented from NobleConnect.Stun.Attribute.

◆ SerializeValues()

override void NobleConnect.Stun.AttributeChangeRequest.SerializeValues	(	BufferView	buffer,
		ReadOnlyByteArray	transactionID
	)

virtual

Transform the string into an ArraySegment of bytes to be sent over the network.

Uses UTF8 encoding

Reimplemented from NobleConnect.Stun.Attribute.
