I have an old laptop lying around and I have been meaning to self host some stuff on it but never got around to it.
My biggest limitation is that I only have WIFI and I do not control the network. It’s basically your default residential WIFI network.
The only thing I actually need is self-hosted cloud. What can I utilize this laptop for?
I would advise against port forwarding without at least a proper firewall with isolation. It is very very dangerous to expose things to the internet and it will backfire at some point, sometimes without your knowledge.
Back when I first started I used a service called kubesail https://kubesail.com/
Now that I have way more hardware I just use a VPS on Linode to route traffic.
