Yeah get that. I do it because my pangolin is segregated so that if that internet facing layer is penetrated, there's not much else they'll have access to. Similarly, if my WiFi is penetrated, there's just a few devices. And many of my services run on Kubernetes distributed and load balanced across a bunch of cheap devices, so it needs reverse proxying at the ingress anyway. And there are a few other reasons for keeping traffic off of the pangolin server or even the router when it's internal to internal, but still be able to use the single domain name for the service, especially with IPv6 not having static IP addresses quite the same way as IPv4, so not wanting to hard code IP addresses or even port assignments in services that back other services like the database server which originally was just running on the NAS, but switching it over to another system only required changing the internal reverse proxy, not every service that used it. I like abstraction like that.
