- [X] I have searched for [existing issues](https://github.com/ionic-team/ionic-framework/issues) that already report this problem, without success.

### Ionic Framework Version

- [ ] v4.x
- [ ] v5.x
- [X] v6.x
- [ ] Nightly

### Current Behavior

On the command `ionic cap run ios -l --external -p 3000` it fails immediately when `npm run ionic:serve -- --host=0.0.0.0 --port=3000` is executed.

```
ERROR] No external network interfaces detected. In order to use the dev server externally you will need one.

Are you connected to a local network?
```

### Expected Behavior

App should be started on the iOS device with live reload.

### Steps to Reproduce

Upgrade to node v18 and run `ionic cap run ios -l --external -p 3000`

### Code Reproduction URL

_No response_

Reproduce the failure with Node v18 using `ionic cap run ios -l --external -p 3000`, then inspect the Ionic CLI entry point that handles external live-reload networking. Trace the network-interface detection used after `npm run ionic:serve -- --host=0.0.0.0 --port=3000`; done means the iOS app starts with live reload on an external interface.
