Dear All: I am using ipfilter to filter the real traffic. I have append many rules to filter the packets. The computer performs very slow after I configured it with these rules. I am wondering what is the speed of ipfilter regarding to the number of rules. btw, when a packet arrives at the interface, does the ipfilter check all the rules one by one and then make a decision whether to admit the packet or drop it? Or the ipfilter buffer all the incoming packets first and use intelligent algorithm to speed up the process?
Thanks a lot! best wishes Tao
