For the very first time i tried to selfhost a static site (lighttpd + duckdns) but I’ve failed… Is it even possible to selfhost a static site from “router 2” while i’m behind two routers? “Router 1” is from ISP and i have no possibility to change any settings except subnet, standard gateway, dhcp on/off and DMZ. -> no port forwarding. "Router 2 is Asus with port-forwarding available and i’m using an OpenVPN configuration on it (if that matters). DuckDNS could see the external ip from R2, but i couldn’t access it.
I use cloudflare tunnel for this purpose. No open ports, no dealing with ISP, no exposing my IP.
yet some people might want less america in their setup and try to avoid services like that.
While this is true, the reader is really the only one that can choose for themselves and Cloudflare is a valid option, even if it isn’t the most purist method available.
