Hardware Considerations
Openreach will install an ONT (Optical Network Termination) device at your premises
The ONT device must be connected to your router’s WAN port via an ethernet cable
Please note that your router will require a WAN port capable of supporting PPPoE
For FTTP services above 100Mbps, we would recommend a Gigabit WAN port on your router
Generic Router Settings
PPP Username & password: This will be provided in your Cerberus documentation
MTU: 1492
VLANs: It is not necessary to apply any VLANs in order to establish your connection
IP Address: Please do not manually enter an IP addresses on the WAN interface of your router as this should be automatically picked up via the PPP connection
IPv6 Considerations: In addition to your public IPv4 address, we will automatically provide you with a /56 IPv6 subnet
DNS Servers: These will be obtained automatically as part of the PPP connection. Our public DNS servers are as follows:
▫ IPv4: 46.37.32.22 and 46.37.33.22.
▫ IPv6: 2a01:5d00:0:40::3 and 2a01:5d00:0:41::3
