[Click] ToHost userlevel

[Bayani Carbone]

Hi, thanks for your help. I am now able to send the packets up to the 
application. However I have now another problem, since I modify the 
destination port in click, when the application answers it does so but 
to with an incorrect source port from the view of the client.
IPRewriter creates a reverse mapping, I read in the doc, and I'm trying 
to use it but I don't seem to receive any packets from the tunnel in 
click. I tried tun -> Print(ok) but see nothing, I also tried the 
example in the KernelTun doc but that doesn't work either. My tunnel 
seems to only work from click to kernel, not the other way around.

Do you have any suggestions?

Thanks
