Hmm, now I understand why it's not working. It seems to be what could 
best be described as an "interesting" setup ! Unfortunately, I think 
in many OS's you can't set the route as required - because really you 
want to be setting your default router as (in Linux IP speak) :
  ip route add default dev eth0
Ie your DomU just spits packets out of the device without considering 
what the IP address of the other end is. I **think** the Dom0 will 
then take care of routing them to their destination. You'll need to 
be able to tell the routers on the "outside" (ie connected to the 
physical ethernet card) network that they can route to your DomU via 
the IP address of the Dom0.
I don't know if Windows or OS X can do this at all, let alone via 
their network config GUIs.
