[Click] click and unreceived ARP responses ...

[Brian Russell]

I am part of a class that is using click for the first time and we're all 
having some problems with it that I hope someone will be helpful enough to 
clarify.  We are writing a VLAN using click and my code uses ARPResponder 
to return a phony MAC address for our contrived IP addressing scheme.  The 
ARP request arrives and the ARPResponder sends out the proper (phony) MAC 
address, but the kernel does not apparently receive the ARP resonse and 
the data packets never get sent into the subnet.  At least, this is what 
we think is happening.  We definitely know that the click program does not receive any data packets.
                                                                                
I think this might be a problem with click or a problem of conflicting 
configurations.  If thie latter is true, what must be adjusted and how 
does it get adjusted?
                                                                                
Thank you very much for your time.
