# Create Guard to Allow Ingress with IP/CIDR

Create guard to allow ingress with IP/CIDR used to make a CloudekaGuard which will allow incoming traffic to pods with certain labels from specified IP addresses or IP ranges (CIDR). Using this syntax, you can control incoming access to your web application from permitted IP addresses or IP ranges, and restrict that access based on specific rules. You can first run the following syntax to create a YAML file with the name allow-ingress-with-cidr.

```bash
nano allow-ingress-with-cidr.yaml
```

Copy and paste the following YAML contents.

```yaml
apiVersion: tenants.cloudeka.ai/v1alpha2
kind: CloudekaGuard
metadata:
  name: allow-ingress-with-port
  namespace: ns1
spec:
  endpointSelector:
    matchLabels:
      app: web-app
  ingress:
  - fromCIDR:
    - 192.168.1.100/32
  - fromCIDRSet:
    - cidr: 192.168.0.0/16
      except:
      - 192.168.1.0/24
```

After pasting the syntax, save the file by pressing Ctrl + O, then press the Enter key and exit the editor by pressing Ctrl + X. The next step is to apply Cloudeka Guard.

```bash
kubectl apply -f allow-ingress-with-cidr.yaml
```
