Egress Gateway using wildcard hosts

Networking

Hi,

Question regarding egress gateway using wildcard hosts.
I followed the wikipedia example in the doc and it is working - “Configure egress gateway traffic to a wildcard host” - https://istio.io/latest/docs/tasks/traffic-management/egress/wildcard-egress-hosts/
I am trying to do the same for our use case ( https://.<our_domain>.com ) but it is not working. I need to allow any https://*.<our_domain>.com
In the doc example, I can see it defines a ServiceEntry with “www.wikipedia.org”
What should we put there if we don’t have a “www.<our_domain>.com” ?

apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
  name: www-wikipedia
spec:
  hosts:
  - www.wikipedia.org
  ports:
  - number: 443
    name: https
    protocol: HTTPS
  resolution: DNS

Thanks,
Luis
