# PublicNetworkConfigurationProps

Properties for public network configuration.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/router-network-interface.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-mediaconnect-alpha/lib/router-network-interface.ts#L95)

## Example

```ts
declare const stack: Stack;
declare const mediaLiveInput: medialive.IInput;

// 1. A public network interface for the SRT input
const networkInterface = new RouterNetworkInterface(stack, 'NetworkInterface', {
  routerNetworkInterfaceName: 'camera-network',
  configuration: RouterNetworkConfiguration.publicNetwork({
    cidr: ['203.0.113.0/24'],
  }),
});

// 2. A router input receiving SRT from an upstream encoder
const input = new RouterInput(stack, 'Input', {
  routerInputName: 'camera-input',
  maximumBitrate: Bitrate.mbps(10),
  routingScope: RoutingScope.REGIONAL,
  tier: RouterInputTier.INPUT_20,
  configuration: RouterInputConfiguration.standard({
    networkInterface,
    protocol: RouterInputProtocol.srtListener({
      port: 9000,
      minimumLatency: Duration.millis(200),
    }),
  }),
});

// 3. A router output delivering to MediaLive
const output = new RouterOutput(stack, 'Output', {
  routerOutputName: 'medialive-output',
  maximumBitrate: Bitrate.mbps(10),
  routingScope: RoutingScope.REGIONAL,
  tier: RouterOutputTier.OUTPUT_20,
  configuration: RouterOutputConfiguration.mediaLiveInput({
    input: mediaLiveInput,
    pipeline: MediaLivePipeline.PIPELINE_0,
  }),
});
```

## Properties

- `cidr`: string[] — CIDR blocks allowed to send inbound traffic to the network interface.

  **Default:** no inbound allowed (outbound only)
