This dilemma is also the subject of this post, in other words how to “bypass” dual NAT using TeamViewer.
On the negative side, all Finnish 4G mobile broadband connections are NAT:ed on the ISP side (exception is enterprise/business subscribers). I’m not a gamer either, so no need for low ping times. We also happen to live quite near a 4G base station, so regular speeds reach about 40Mbit/s+. This was by far the most bang for the buck. In the end, I ended up with a 50/50 Mbit/s 4G mobile broadband connection which is shared through a 4G router (which I already owned). Fiber optics would’ve been an option (fast and reliable), but it’s rather expensive compared to the other alternatives. Our old place had VDSL, but now I got to choose what I want.
Among many other things, this meant changes to the Internet connectivity. During the summer we moved from an apartment to a house.
