### Software

Each OneDevice ships pre-installed with the OneFirewall application, maintained by OneFirewall Alliance.

## Step 1: Connect the Device

1. Connect your existing internet cable to **NIC-W** (the WAN port previously used for internet access).
2. Use **NIC-L** to access the internet through the device.

Behind the scenes, the device performs:

* Network bridging
* Traffic monitoring
* Threat detection and prevention

**NIC-C** maintains a secure connection to the OneFirewall Server (Console/WCF), used for centralized monitoring, management, and performance oversight of your OneDevice.

## Notes

* Can be installed either before or after your current router. Contact the support team to discuss alternatives for your topology.
