I've got another: I don't get a real IPv4 adress from my provider it's all carrier nat on IPv4. On IPv6 I get a direct connection though. The carrier nat is often slow and and I cant forward IPv4 ports. Using mullvad via IPv6 and IPv6 NAT on my router I can route around the carrier and get much better IPv4 Bandwidth and Peering at the cost of a a worse latency (though it goes from 7 to 25ms for the average game) so it's hardly an Issue. That and I can pirate as much as I want with it in germany.
