NAT yes, of course.

proxy arp, no. If you have a route like "route add default dev eth0"
this will cause all packets to be adressed to the broadcast MAC
address. All other ethernet devices on the same segment should get
packets labelled that way because they listen for both their own MAC
address and the broadcast MAC address.
