Help understanding Reverse Proxies (infosec.pub)

I have a noob question but seem overwhelmed with all the information I get about it. Basically, why do I need a reverse proxy if all my services are not public? Every guide or video for self hosting there’s always talk of a reverse proxy, have been doing it wrong?

Here’s my setup: I have proxmox running with LXC containers and VM’s for different services some have docker. I have HAProxy on PfSense with a wildcard cert. and the built-in dns resolver, and I vpn home every time I need something.

Have I be going about this the wrong way? Would I benefit from Nginx or traefik? Or is HAProxy enough? Sorry for the stupid question, I’m like a kid with a new toy and overwhelming myself.

I did avoid them for a long time. Once I started to figure out how to self certify for https NPM became very helpful. DNS challenge does not require you to open any ports. you need a domain that supports dns challenge, though. Pointing cname to local ip of reverse proxy. And some routers may require rebind protection entry for that domain. Afterward: https and nice names for all my local only services.
