Rancher IPWhitelist?

I know it’s probably posted here, but can’t find it. I’ve sucessfully deplouyed Rancher via Helm/Traefik but only to find out that it’s open to the Internet. How can I add an annotation to add an ipwhitelist to allow access from my local LAN?

Traefik has an IPAllowlist middleware you can use: Traefik HTTP Middlewares IPAllowList - Traefik
