It’s mostly working fine for me.

An alternative I tried before was just whitelisting which IPs are allowed to access specific ingresses, but having the ingress listen on both public/private networks. I like having a separate ingress controller better because I know the ingress isn’t accessible at all from a public ip. It keeps the logs separated as well.

Another alternative would be an external load balancer or reverse proxy that can access your cluster. It’d act as the “public” ingress, but would need to be configured to allow specific hostnames/services through.
