# Use Cellular Gateways for WAN Failover

Cellular Gateways support WAN failover mode, which enables the gateway to act as an uplink to your existing network. In WAN failover mode, the Gateway’s cellular connection will act as a failover, helping ensure that your security devices remain online and operational even when your primary network experiences downtime.

{% hint style="warning" %}
The cellular connection will remain active in WAN failover mode and consume minimal data. When the wired Ethernet connection fails, the cellular connection acts as a failover, keeping the gateway and any connected devices online.

## Enable WAN mode

#### Outdoor Cellular Gateway

WAN failover mode works automatically on the GC31-E.

{% stepper %}
{% step %}
**Plug the Ethernet cable into the PoE In port, and the gateway will automatically detect the uplink and use the wired connection.**
{% endstep %}

{% step %}
**Once the gateway receives an IP address from the wired network, a WAN badge will appear on the gateway details page, indicating that the connection was successful and the gateway is now functioning in WAN failover mode.**
{% endstep %}

{% step %}
**Verkada devices need to be connected downstream on the PoE Out port of the cellular gateway and get their IP addresses from the gateway.**

{% hint style="danger" %}
All downstream devices must receive their IP address & DHCP information from the gateway before a WAN failover can occur.
{% endhint %}
{% endstep %}
{% endstepper %}

#### Indoor Cellular Gateway

To enable WAN failover mode on the GC31, configure PoE Out Port 2 as an uplink.

{% stepper %}
{% step %}
**In Verkada Command, go to All Products > Gateways.**
{% endstep %}

{% step %}
**Select the gateway you want to configure.**
{% endstep %}

{% step %}
**In the top right, click Settings.**
{% endstep %}

{% step %}
**Under Network > Port 2 Configuration, select Wide Area Network (WAN).**
{% endstep %}

{% step %}
**Click Apply to save the configuration.**
{% endstep %}

{% step %}
**Click Confirm, and the device will reboot. PoE port 2 will now act as a WAN port.**
{% endstep %}

{% step %}
**Plug the Ethernet cable into PoE port 2.**

{% endstep %}

{% step %}
**Verkada devices need to be connected downstream on port 1 of the cellular gateway and get their IP addresses from the gateway.**
{% endstep %}

{% step %}
**When the device receives an IP from the wired network, a WAN badge will appear on the gateway details page.**
