No, it won't. All that's needed is an inbound route to your router, and NAT can't prevent that route from existing. It doesn't matter if you have ISP control or not.
I'm not seeing any gre packets from you. Are you having trouble getting the tunnel working?
NAT _will_ stop inbound connections in practice, unless you control the ISP. So in practice NAT provides more than enough security for typical SOHO users.

Exactly. Which means that you need (in practice) to control the ISP for this attack to work.
