Hi,

I am sorry to say, I wasn't able to get that to work either (partially 
because I don't need it in my configuration). But I do think that you can 
follow the advanced routing howto more closely on that one when you use the 
interface to the local network, as the IP-adress is translated back to the 
internal adress long before it travels through this interface.
So in theory:
#example from the advanced routing-howto, slightly changed
tc filter add dev eth0 parent 10:0 protocol ip prio 25 u32 match ip dst \
        150.151.0.0 flowid 10:100

This should work (with the previous rules being pretty much the same as I 
gave them).
