!!! attention
For HTTPS to HTTPS redirects is mandatory the SSL Certificate defined in the Secret, located in the TLS section of Ingress, contains both FQDN in the common name of the certificate.
### Denylist source range
You can specify blocked client IP source ranges through the `nginx.ingress.kubernetes.io/denylist-source-range` annotation.
The value is a comma separated list of [CIDRs](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing), e.g. `10.0.0.0/24,172.10.0.1`.
To configure this setting globally for all Ingress rules, the `denylist-source-range` value may be set in the [NGINX ConfigMap](./configmap.md#denylist-source-range).
!!! note
Adding an annotation to an Ingress rule overrides any global restriction.
### Whitelist source range
You can specify allowed client IP source ranges through the `nginx.ingress.kubernetes.io/whitelist-source-range` annotation.

Sets the default denylisted IPs for each `server` block. This can be overwritten by an annotation on an Ingress rule.
