Hi Nitin,

I know that u r trying to implement a firewall so I guess u r the best person to ask this ? to. How have u gotten around reading the headers and classifying them accordingly. I know that we have the 8 bit L3-proto after the L2-Source Address. However I have been unable to read the proto byte successfully. I will really appreciate it if you could gimme some pointers on this.

Regards, Tabrez
