I use istio:

istioctl version
client version: 1.11.2
control plane version: 1.11.2
data plane version: none

k8s:

kubectl version --short
Client Version: v1.21.5
Server Version: v1.21.5

When I'm deploying my app (nginx+app) nginx healthcheck has fail.

 access forbidden by rule, client: 127.0.0.6

I understand why, but can't understand what is 127.0.0.6 in istio. I found only 1 links on github (https://github.com/istio/istio/issues/29603). My app has service and declare port. But still can't figure it out how to running healthcheck on 127.0.0.1 and what is 127.0.0.6
