Can you bring me some light on why packets from 172.18.0.13 are crossing ppp0 whithout being masqueraded?
I can't tell for sure (you did not provide your IP addresses per say) but it looks like the traffic is from your internal network and headed for your external ppp0 interface its self.
Seeing as how you did not actually provide your IPs I'm guessing based on the fact that you have a route of 200.198.184.204/32 on your ppp0 interface that said IP is bound to said interface. If this is the case, it is possible that the traffic is entering the kernel and going up the network stack directly rather than being forwarded like you would expect.
I believe this is coming back to the fact that IPs are not bound to an interface per say, but rather the computer and that in some situations any interface in the system will take the traffic and pass it up in to the network with out forwarding it over to the interface that it is bound to before it takes the traffic and passes it higher in the networking stack.
