You can do this by proxy-arping; see "man arp":
-s hostname ether_addr
Create an ARP entry for the host called hostname with =20
the Ether-
net address ether_addr. The Ethernet address is given =20
as six hex
bytes separated by colons. The entry will be permanent =20=
unless
the word temp is given in the command. If the word pub =20=
is given,
the entry will be ``published''; i.e., this system will =20=
act as an
ARP server, responding to requests for hostname even =20
though the
host address is not its own. In this case the =20
ether_addr can be
given as auto in which case the interfaces on this host =20=
will be
examined, and if one of them is found to occupy the =20
same subnet,
its Ethernet address will be used. If the only keyword =20=
is also
specified, this will create a ``published (proxy =20
only)'' entry.
This type of entry is created automatically if arp =20
detects that a
routing table entry for hostname already exists.
