FTTP Routers - Generic Advice & Settings

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, you will require a Gigabit WAN port on your router and sufficient router performance in order to support the full speed of your connection.

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 FTTP internet connection.
  
  
  

• IPv4 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
