Try specifying the physical device the packets are going out, rather 
than the bridge, in your postrouting rule.

Apparently you also need an ebtables rule to prevent the return packets 
from being merely bridged?

I'd test it, but have a look if you get the outbound traffic working and 
return traffic doesn't.
