[Click] CLICK checkarpheader or arpfaker problem or working as intended?

[Eddie Kohler]

Skatsu,

One potential problem with these ARPFakers is that you shouldn't use group 
Ethernet addresses.

The problem with your configuration is that you're sending ARP responses, 
generated by ARPFaker, into an ARP responder.  The responder ignores 
responses; it only cares about queries.
