Hi, I am capturing packets using netfilters. I am modifying the packets and I want to give it "up the linux IP stack" in the kernel. The implementation has to been done as a loadable module. I have a problem here, I don't find any kernel exported symbol which can be used to send the modified stack up the stack and give it to the IP module. Kindly tell me if there is any way to do that. I thought abt compiling the code which I have written along with the kernel and use the kernel functions directly, but it is not portable. Kindly tell me how to proceed. cheers Suresh
