CAN acceptance filtering (LPC4357)

There are some discussion to similar subject, but they do not solve my problem.
I am using acceptance filter:

e.g. identifier  0x64   

-> all is working, when the CAN-message does not use an extended frame. With extended frame I do not get this message. So I thougt to change the identifier to 0x64 + (0x1<<30) to mark the extended frame. But this does not help to get the message.
e.g. identifier 0x1234  -> all is working. This message can be only sended as extended frame. It is not necessary to modify the identifier with (0x1<<30)
1) is there any way to get all messages from a identifier (e.g. 0x100) independed from the CAN- format 2.0a or 2.0b ?

2) If not, how I have to define the identifier to get messages sended in the extended format ?

3) Do I need two filter - one for 2.0A and the other for 2.0b ?
Thanks for any help in advance.

Andreas
