I have tried all IPs in the range, but I have not tried different
netmasks.  Thanks for that tip.

Could you please post the output of 'route -n', 'ip route' and 'ip neigh
show' as well as any 'ip route [add|del|*]' commands you run?

I really believe that either the kernel thinks there are spoofed IPs or
- most likely - that my routing table is junk.

Here is a quote from http://www.sjdjweis.com/linux/proxyarp/ which is
why I set both the same:
