Gratuitous ARP

That is exactly the issue. The wireless device uses proxy arp and responds
on the MAC address of the client which causes the NAK to occur. I am
looking to shut off the DHCPDECLINE functionality in this circumstance.

The ARP isn't gratuitous. The client is supposed to ARP for the address and
send a DHCPDECLINE if it's in use. I take it you are having a problem with
this behavior-can you describe what's going on?
