I have a small homelab that is not open to the internet. I am considering the following setup. Please let me know if there are any glaring issues or if I am over complicating things.

• I want to setup a reverse proxy in the cloud that will also act as a certificate authority. (I want to limit who can access the server to a small group of people.)

• I will setup a vpn from a raspberry pi in my home to the reverse proxy in the cloud.

• The traffic will pass from the raspberry pi vpn to my homelab.

I am not sure if I need the raspberry pi. I like the cloud as the reverse proxy as I do not have a static IP. I would just get a cheap vps from hetzner or something like that.
