the 'packet' which arrives from the kernel, is through a library called libipq and it doesnt return the packet as such but some structure which contains the harware address, data lenght , payload(optional), in interface, out interface, hook type etc. There is no mention of ip header anywhere..the most i get out of the original packet is the payload. I was asking if i can get the source and destination ip of the packet which arrives through the lipipq function: ipq_get_packet(char* buf).
