"ip proxy-arp" should be always disabled, unless you specifically know that
you need it.

For a normal point-to-point link between routers, you'll never need it.

(Having proxy-arp on-by-default is one of the major design errors that
Cisco did - it's seen as a "convenience", because it "makes things works"
that would break otherwise.  In reality, all it does is "it hides problems",
because mis-configured systems still work - until the point where they no
longer work, and then it's much harder to find where the brokenness is)


To me, this sounds a bit as if the *Radio* is answering the ARP requests
on its own, for some sort of "management interface" or so.
