How to set up IP whitelist on DigitalOcean Kubernetes?

I’ve set up whitelist annotation on my ingress, on Kubernetes cluster, but in logs there are wrong IP-s, so it doesn’t work.

Here is ingress configuration:

kind: Ingress
  name: test
  annotations: "nginx" ',X.X.X.X'
    - host:
          - backend:
              serviceName: service
              servicePort: 80

And testing configuration:

$ curl


$ curl -I
HTTP/1.1 403 Forbidden
Server: openresty/
Date: Mon, 02 Mar 2020 12:45:24 GMT
Content-Type: text/html
Content-Length: 159
Connection: keep-alive
Strict-Transport-Security: max-age=15724800; includeSubDomains

And logs from ingress-controller: - - [02/Mar/2020:12:45:24 +0000] "HEAD / HTTP/1.1" 403 0 "-" "curl/7.65.3" 84 0.000 [service-80] [] - - - - 

So my IP was X.X.X.X and ingress controller received Why is it happening and how can I fix it?
