First, your cross posting is offensive. Don't do that. Limited to linux-net.

2.2 does automagic proxy arp -- it'll answer for all addresses that it
forwards too on another address. Try
echo 0 > /proc/sys/net/ipv4/conf/*/proxy_arp
after you added the pub ARP entries (arp will automatically enable it).
The public arp entry should still work with proxy_arp turned off
(strange, isn't it? it should be really named auto_proxy_arp and not changed
by arp settings)
