I too had problems with proxy arp.
I got it to work (with help) by doing a 'arp -i eth0 -s xxx.xxx.xxx.xxx 00:00:00:00:00:00 pub
Where eth0 is the outside if and xxx.xxx.xxx.xxx is the outside IP address. And of cause the correct MAC address of that interface.
But it dident work before I added a route!!!! 'route add -host xxx.xxx.xxx.xxx eth1'
Where eth1 is the inside of my firewall.
Hope you can make it work.
Regards

I read the man page for arp. It says that the kernel does automagic arp if a route exists between the subnets.
Did you also do 'man 7 arp'? That page says that the interface in question has to have proxy arp enabled. It's a sysctl thing, check /proc/sys/net/ipv4/conf/<IF>/proxy_arp.
