Hello,

sorry for the delay. I have used something like this:

router:
ifconfig eth0 172.16.7.42 netmask 255.255.255.0 broadcast 172.16.7.255
route add default gw 172.16.7.1
ifconfig eth1 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255
ifconfig eth2 192.168.1.1 netmask 255.255.255.255 -broadcast
route add -host 192.168.1.17 device eth2
route add -host 192.168.1.18 device eth2
route add -host 192.168.1.19 device eth2
echo 1 > /proc/sys/net/ipv4/conf/eth1/proxy_arp
echo 1 > /proc/sys/net/ipv4/conf/eth2/proxy_arp

The network 192.168.1.0/24 is divided into two parts, ip addresses 
192.168.1.17, .18, .19 are connected to eth2, other ip addresses to eth1.

192.168.1.17:
ifconfig eth0 192.168.1.17 netmask 255.255.255.0 broadcast 192.168.1.255
route add default gw 192.168.1.1

traceroute from 192.168.1.17 do 192.168.1.2:
  1  192.168.1.1  1.08 ms  0.73 ms  0.723 ms
  2  192.168.1.2  0.85 ms  0.77 ms  0.715 ms

"arp -an" at 192.168.1.17:
? (192.168.1.1) at 00:00:B4:9F:A4:58 [ether] on eth0
? (192.168.1.2) at 00:00:B4:9F:A4:58 [ether] on eth0
(note the same MAC address)

HTH,
