Ah - that would probably work. He would use one helper at the source,
pointing to the broadcast address of the WAN destination router.
There, he could use 4 helpers to forward this one. Yes, this *could*
work, but I remember trying something along these lines and failing
miserably. If I remember well, it had something to do with Ethernet
frames not being broadcast when they hit the interface, but my
recollection is vague. It's worth a shot, though.

I still think this is the best approach in this case, as the feature I
recommended was designed to solve the *exact* problem described.
