Hello!
I have a task to forward outgoing packets to a local transparent proxy server.
I have decided to use NKE filter (similarly to what ipfw forward
does). However, I am not sure, how to do that. The point is to not
modify the packets (destination address, port), but yet make the proxy
application receive them. I am not exactly sure if this is possible to
implement (but somehow ipfw does that).
Could you briefly advice me how to do this?
Earlier I have developed a Socket level NKE, but it was modifying HTTP
data "in-house" without delegating the work to a usermode application.
So, basically, this, and a tcplognke sample code are the only examples
i am familiar with.
I suppose to solve my task i would need to write an ip level filter
(or would it be possible using socket level nke?). But how to do the
proxy forwarding mechanism?
Thank you
