I use a VPS as a homelab gateway of sorts from the outside.
Essentially, the VPS runs a Wireguard server that I connect to on my OPNSense Router. The VPS then reverse-proxies all incoming traffic through the tunnel to my homelab. All my DNS entries point to the VPS’s IP. This pretty much gives me a static IP, hides my real IP, and lets me do some light caching on the VPS. Kind of like a DIY cloudflare.
I also run Uptime Kuma on the VPS, since it will continue to work if my local network is down.
