virtual BOOL PNatMethod::GetExternalAddress | ( | PIPSocket::Address & | externalAddress, | |
const PTimeInterval & | maxAge = 1000 | |||
) | [pure virtual] |
GetExternalAddress Get the acquired External IP Address.
maxAge | External address of router Maximum age for caching |
Implemented in PSTUNClient.
virtual BOOL PNatMethod::CreateSocketPair | ( | PUDPSocket *& | socket1, | |
PUDPSocket *& | socket2 | |||
) | [pure virtual] |
CreateSocketPair Create the UDP Socket pair
Implemented in PSTUNClient.
virtual BOOL PNatMethod::IsAvailable | ( | ) | [inline, virtual] |
Returns whether the Nat Method is ready and available in assisting in NAT Traversal. The principal is function is to allow the EP to detect various methods and if a method is detected then this method is available for NAT traversal The Order of adding to the PNstStrategy determines which method is used
Reimplemented in PSTUNClient.
virtual void PNatMethod::SetPortRanges | ( | WORD | portBase, | |
WORD | portMax = 0 , |

WORD | portPairBase = 0 , |
|||
WORD | portPairMax = 0 | |||
) | [virtual] |
Set the port ranges to be used on local machine. Note that the ports used on the NAT router may not be the same unless some form of port forwarding is present.
If the port base is zero then standard operating system port allocation method is used.
If the max port is zero then it will be automatically set to the port base + 99.
portMax | Single socket port number base |
portPairBase | Single socket port number max |
portPairMax | Socket pair port number base Socket pair port number max |
