Is there a way to restrict access to a kubernetes service only via vpn

[EzekielHub]

i am trying to expose a service only via vpn so i want to give the ingress gateway a internal private ip instead not a public ip. So only people on the private network can access the service.

for example in other providers you have a way to do it so your service get assinged to a private ip, i dont know if it possible in linode. Have done researches but havent found anything for linode.
Is there anyone that as an idea or has done something similar.

[How would I setup kuberentes ingress to for VPN-only access?]

somthing like this for linode.
service.annotations."service.beta.kubernetes.io/azure-load-balancer-internal"=true
service.kubernetes.io/ibm-load-balancer-cloud-provider-ip-type: "private"

Thanks in advance
