Router Port vs VPS Reverse Proxy (lemmy.primboard.de)

„Inspired“ from https://lemmy.world/post/287146 and many related questions (also on reddit before).

Why don‘t people like opening Port 443 on their Homerouter? An open Port itself is not a vulnerability because nothing is listening on it, therefore there cannot be any connection established. When forwarding Port 443 From Router to e.g. The Homeservers LoadBalancer / Proxy, this Proxy is the final resolver anyways.

So why doing the more complex and more error prone Route via the VPS / Tailscale / CloudFlare?

I did that some years ago too, but just because i did not have an static IPv4 at home. But speeds were awful and i switched to Routerport + DynDNS and now everything is super performant.

do you know for sure that nothing is listening on it? Do you scan every device you connect to your network?

This doesn’t really apply if you’re port forwarding to a specific device. In that case you know that you have told your firewall to forward port 80 & 443 (for example) to your web server and you know what ports that has open. I would not be using UPNP on the other hand as that seems dangerous especially in the IOT era.
