Thank you for all the great responses, I've had the chance to take a look at all suggestions. My research team has been trying to find out if a packet crafter has been created yet that can create ESP packets. Is this at all possible? We tried writing one but it ultimately failed. Has anyone seen one of these floating around? NEMESIS and the like currently do not have that sort of functionality.
