Hey, I just decided to run a DNS server and a couple of web services on my lan from a raspberry pi over the weekend. I used Nginx for the reverse proxy so all of the services could be addressable without port numbers. It was very easy to set up, it's funny how when you learn something new, you start seeing it all over the place.

That's a great exercise in self-hosting. Nginx is definitely everywhere - probably 95%+ of SaaS and websites you hit are running it somewhere.
