@property
def TUNNEL_TYPE(self):

Undocumented

def __init__(self, tunnelRemote, tunnelLocal, pi):

Parameters	tunnelRemote	The source address for UDP datagrams originated from this helper. This is an IPv4 dotted-quad string. (type: `bytes`)
	tunnelLocal	The destination address for UDP datagrams originated from this helper. This is an IPv4 dotted-quad string. (type: `bytes`)
	pi	A flag indicating whether this helper will generate and consume a protocol information (PI) header. (type: `bool`)

def encapsulate(self, source, destination, payload):

Construct an ethernet frame containing an ip datagram containing a udp datagram containing the given application-level payload.

Parameters	source	The source port for the UDP datagram being encapsulated. (type: `int`)
	destination	The destination port for the UDP datagram being encapsulated. (type: `int`)
	payload	The application data to include in the udp datagram. (type: `bytes`)
Returns	An ethernet frame. (type: `bytes`)

def parser(self):

Get a function for parsing a datagram read from a tap device.

Returns A function which accepts a datagram exactly as might be read from a tap device. The datagram is expected to ultimately carry a UDP datagram. When called, it returns a list of tuples. Each tuple has the UDP application data as the first element and the sender address as the second element.

Method	__init__
Method	encapsulate	Construct an ethernet frame containing an ip datagram containing a udp datagram containing the given application-level payload.
