I have read many posts in this subreddit and so many recommend using a domain (buying it) and then registering DNS.
Maybe I misunderstood because I’m new, but in theory isn’t it enough to use a DNS in lan like pihole, and then from the client browser using Wireguard simply write the domain defined on pihole? (Maybe even configuring nginx to have all the ports pointing to the correct services)
Am I wrong?
One reason is that a lot of mobile browsers won’t resolve local-only domains or even IP addresses unless you explicitly put https:// in front of it, every time. Instead they treat them as a search and you end up searching for your local domain in a search engine. It’s a pain in the ass and having a public, registered domain gets them to properly resolve even when your local services live on a non-public subdomain.
