[Click] Could configure NAT in user level?

[Dongyu Yang]

Hi Eddie:

    Thanks for your help!

    Now I want to know, how it gets the Packet from the kernel, and send the
packet to kernel? Does ToHost.u must be used with FromHost.u? And I want to
know the difference between KernelTun and FromHost.u ToHost.u?
