Settings to use UDR instead of Sky router

[ElJefe73]

Hi all. I'm new to Sky and want to use my UniFi Dream Router (UDR) to manage the home network. From what I've read, others have done this. I'm wondering if someone can provide a step-by-step instruction on what advanced settings need to be done for the UDR to work with the Sky router. My previous ISP used PPPoE, but from what I've read Sky use a different approach. 

Hardware: Sky Max Hub (HomeHub6) and UniFi Dream Router

Connection: Sky Full Fibre Ultrafast Plus

@ElJefe73 connecting the Unfi unit behind the Sky hub creates a double NAT set up but should not need any cong[figuration as the Sky hub manages the WAN connection.

If you want to connect your UDP directly to the ONT then Sky require routers to authenticate in a different way from mostother ISPs. The primary method uses DHCP v4 Option61 with a standard string anything@skydsl|anything I am not clear if your router supports that but I found this post which says it can be set up. There is a second authentication method which works on around 75% of lines which is DHCPv6 PD
