[Click] Filtering TCP ACks

[Roberto Riggio]

Hi,

I have I problem in filtering the TCP ACKs. I'm generating traffic between 
two nodes:

A -> B

I would like to filter the ACk at node A. However filtering the packets using 
the IPCLassifier element is not working since the ACK field is set to TRUE 
even for the segments travelling from A to B (in this case the ACK number is 0)

The only workaround that I've managed to find is to use the element CheckLength
in order to filter all the packets longer the 100 byte. In my particular case 
such an approach is fine, but I'm wondering if there is a correct solution to my
problem.

Bye
