Hello, I need help setting this up. It would be greatly appreciated!
I have a home network with Home Assistant on it. My home network has two WAN’s.
WAN1 is fiber direct
WAN2 is Cellular Backup (failover WAN)
At home I have a Home Assistant server.
Additionally I have a VPS sever that runs a web-server. What I ultimately want to do, is make Home Assistant and the VPS Web Server be able to talk back and forth via Home Assistants API and my own that I setup. I could do this easily by port forwarding, however CGNAT blocks this when switched to cellular backup WAN. Additionally port forwarding exposes my home internet and I would rather just not do that.
So, I figured I could create a Wireguard Server on my VPS and connect to it on my Home Assistant Server which would allow my VPS to access the local internal IP of the Home Assistant Server of : 10.0.1.102:8098 (8098 being the home assistant port).
Can someone guide me? Please and thank you :).
