As far as I understand your question: you can change the TOS based on the incoming interface (and lots of other options). And I think it isn't usefull to reset the TOS field when you send out the packets into the internet, because most routers won't use the field and simply ignore it. When a packets comes back, you should route it dependand on the destination, not on the TOS field because that can be anything. I hope I haven't told complete nonsense. Tung
