I've been looking a lot into self-hosting recently. In my area, it seems that no LTE ISP will give you an suitable connection: they're all either behind a NAT, or behind a heavy firewall.

Now sure, I can rent a VPS to forward traffic to my device via a VPN. But that's not really self-hosted any more.

It seems a decentralised internet is becoming harder and harder with each passing day -- hosting stuff on an rpi at home is no longer possible.
