And it's not as though fixing it is hard. I wrote the code and attached it to the radar rdar://4422761 last January.

Your default-route scheme certainly make this work, but wasn't viable for us since the server couldn't be a router (for various reasons).

Your choices are to put the dump server on a different subnet (the  
router will obviously forward in this case, as that what it must do)  
or write your own arp code in a modified kernel. That's what we did,  
since we already had kernel mods. Most folks won't go that way :)

I've run into this for as long as I can remember having dumps.
My workaround is to set the default route to be the dump server.
This works best when you are planning in advance to crash the
machine :)
