Enabling Router mode will allow the UFiber ONU to perform NAT and DHCP services, eliminating the need for a separate router connected to the LAN port of the ONU. The current firmware release supports IPv4 NAT (IPv6 support will be added in a future release).

Many different devices can be connected to an ONU to provide connectivity and features for your users. See UFiber GPON - Getting Started for more details.
