The GetExternalSocketName method sets the name of the socket for the connection. Call this method only if the caller is emulating the connection.
HRESULT SetSocketName( [in] LPSOCKADDR Address, [in] DWORD AddressLength );
Pointer to a sockaddr structure that contains the socket address.
Length, in bytes, of the Address parameter.
This method can return one of these values.
The method succeeded.
The socket is already bound.
An invalid argument was provided to this method.
On regular connections, the Microsoft Firewall service calls the getsockname Winsock function on the external socket and passes this information to the Forefront TMG Client or Firewall Client computer. For an emulated connection, there is no external socket, or the external socket is known only to the filter. The filter is required to call this method and set the socket name.
When there is no connection, it is advisable to return an IP address of the Firewall service (external or internal as appropriate) because the client application may use this information to publish the address.
