Hi all
I need to send and receive RAW IP packets on a Win2K/XP box. That is: I want a specific process in the system (which I write, of course) to have a different IP than that of the computer's. This process will be sending RAW IP packets, and will receive packets directed to "it's" IP address.
How do I go about this?
I thought about some fiddling with RAS, creating a "dial connection" to a PPP server which will give me my IP, but for that I need a programmable PPP client linked in my process. Does anyone know of such a thing?
I've also thought about adding another "virtual" interface onto my ethernet card, with a different IP, use it only from this process, and then opening a RAW-IP-mode winsock socket on that interface and IP. However, is this allowed? What about ARP on other machines in the network? How do I do this, anyhow? How do I *receive* packets, before windows "Eats" them?
I understand this is a hard one, and calls for real Gurus, so I've graded it accordingly...

Could you write your application to listen only in a port?
In NT Networking, in any IP ( phisical and virtual ) you can enable and disable some ports.
If you disable all the unnecesary ports of your phisical IP and let opened in the virtual IP the port of your application, NT doesn't eat your packets....
