It sounds like you're saying that packets on a network directly connected
to the m0n0 are going first to some other router, getting transformed by
NAT, and *then* going to the m0n0.  Why is that, or am I misunderstanding

You can pass whatever you want through the tunnel, and it doesn't sound
like you need to block anything from it in this configuration.
