## OPNSense demo
# OPNSense Demo
Download the virtualbox snapshot from {{TODO URL}}
This example demonstrate how to manage an Opnsense server with harmony.
Start the virtualbox image
todo: add more info
This virtualbox image is configured to use a bridge on the host's physical interface, make sure the bridge is up and the virtual machine can reach internet.
## Demo instructions
Credentials are opnsense default (root/opnsense)
todo: add detailed instructions
Run the project with the correct ip address on the command line :
- setup the example execution environment
- setup your system configuration
- topology
- scores
- secrets
- build
- execute
- verify/inspect
## Example execution
See [learning tool documentation](./scripts/README.md)
```bash
cargo run -p example-opnsense -- 192.168.5.229
```

# Example scripts
Scripts included in this directory have 3 purposes:
- automate initial setup of localhost or VM (nested virtualization) for this example
- prototype a solution for an 'OpensenseLocalhostTopology'
- prototype
## Remarks
- A nested VM setup should be safer
## Automation
### Localhost learning environment
