That's because of step 1. Setting "/proc/sys/net/ipv4/conf/<if>/proxy_arp"
to 1 causes the system to answer any ARP requests which:

1. are received on the corresponding interface, and
2. are for an IP address to which the system has a route via a
different interface.

Basically, you want to use either step 1 or 2, but probably not both.
