I have a domain which points to my router (over dynamic DNS). My parents’ Router connects to my home network via Wireguard using that. All my services have subdomains, for which I have set static DNS records that point to the local address (192.168…) of my server. This way, I only need to expose Wireguard to the public.
My own wordpress website to host recipes on a Synology NAS. Unfortunately, the built in NGINX server has some default configuration (from Synology) so that it cannot properly serve the Wordpress REST API. The NAS is (according to Synology) to weak to run a container, where I could easily run a separarate server. So I gave up and just recently bought a Dell Optiplex Micro, which I will turn into my new homeserver. Guess I will keep the Synology for storage though.
Using this as well. Works pretty solid so far.
