Subject: Re:Re: How to set the filtering rules for drop the packets

thanks for your reply , 

 my NIC is intel X540-T1, when i set dst-port filter first ,suceess, but then set src-port filter failed。

That is to say the filter rule src-port and dis-port can't set together。

There are any other ways to filter the packets that srcport is 80 or dstport is 80?
                                              
                                                                                                                 monney
