Do you know ho to configure the port to get the whole package?

Thanks

Today I tried to open the program in a Windows Vista machine, and it didn’t logged anything, I recompiled it with some printfs in several parts of the code just to know where the program was not working and I noticed it was not reaching this if

void ProcessPacket(unsigned char* Buffer, int Size)
{
iphdr = (IPV4_HDR *)Buffer;
if(iphdr->ip_protocol==6){
InterceptPacket(Buffer,Size);
}

}

it only checks if it is tcp because those are the packets I’m interested on, but I think the problem is that the machine could probably be using ipv6, so, my question is, how different are ipv6 headers and how can I distinguish ipv6 from ipv4?

thanks for yout time
