DHCP server

When you use a static IP address, Cloudflare One Appliance (formerly Magic WAN Connector) can also act as a DHCP server in your network. To enable this feature:

Log in to Cloudflare One, and go to Networks.
Go to Connectors > Appliances > Profiles.

Select the Cloudflare One Appliance you want to configure > Edit.
Select Network Configuration > LAN configuration.
In LAN configuration, select the LAN where you want to enable DHCP server.
Select Edit.
Under Static addressing, select This is a DHCP Server. You also have to specify:
- The DNS server address. You can have more than one IP address. Select Add DNS Server for each server you want to add.
- The DHCP pool start
- The DHCP pool end

Create a PUT request to update the LAN where you want to enable DHCP server:

Example:
