I have a PC I have installed Portainer on, with various docker services (home assistant, jellyfin, etc…) with an ISP supplied router fixing various device IP addresses and reaching out to dyndns.
I really want to move everything over to HTTPS connections by supplying certificates, tls termination, etc .
The issue I have is self signed certificates mean I have to manage certificate deployment to everything in the house.
I figure I need to link a domain to the DynDNS entry and arrange certs for the domain. However I can’t make the link function and everywhere wants >£100 to generate a certificate.
How are people solving this issue?
You can setup a VPS between the internet and your home network to limit the exposition of your home network. When a client pings yourdomain.com, it sees the ip of the VPS and not the IP of your home network.
Otherwise, a VPN + home CA server will make your home network accessible and encrypted as well
