Eh, he does nothing with proxy-arp.
So I am really puzzled here. Especially the MASQ entries? Why? What?

Glynn, would you care to explain your setup, more like what are you
trying to do?
Because: yes: you can have a proxy-arp "bridge" (remember, it will not
learn anything) using a tunnel, connecting the same subnets. Both ends
of the tunnel must exactly know where each system resides with respect
to the tunnel. And no, this has nothing to do with netfilter,
masquerading, etc. . You still are in the pure routing domain.
