Istio-ingressgateway && Istio-egressgateway pods fail while enable firewall but success while disable firewall although i opened all needed port?

Service Mesh with Istio
#1

while installing istio on on-premises kubernetes cluster i face error like this:
kubelet Readiness probe failed: Get “http://10.244.0.55:15021/healthz/ready”: dial tcp 10.244.0.55:15021: connect: connection refused
although i opened port 15021
but this error doesn’t appear while firewall is disabled

Hi @Ahmed-Abd-El-Salam,
The issue is on the firewall rules them. :slight_smile: Please share with us the configuration on the firewall
