I only use cloudflare for Home Assistant and Bitwarden, just not to have many layers where a problem could happen as those 2 services are critical.
I rent a VPS with Authentik and Wireguard for the rest, like Nextcloud, Emby etc. But it’s huge hassle with ssl certificates, especially with Let’s encrypt ones.
But honestly I’ve never used it, except the HA and Bitwarden. When I’m on vacation I just want to experience as much as I can from the location I’m at. And I’m trying to stay away from computers when I’m away. And my family really does not care about Emby. So I’ll probably stop it.
And BTW you probably shouldn’t pass video streams through cloudflare as it’s against their TOS. Although I didn’t hear about anyone who has been banned.
If you want simple and no hassle solution, just use Tailscale or ZeroTier.
