sure illegal content can be accessed over a vpn without port forwarding, but when someone is hosting a child porn site over a mullvad ip, that is clearly a larger problem

although people hosting illegal content using port forwarding is likely one of the reasons they removed it, so its a tricky problem

If you use cloudflare, there’s a docker container to update your sites DNS records to your current dynamic IP (also cloudflare is good ddos protection) https://github.com/oznu/docker-cloudflare-ddns
