UniFi fiber settings

[Paddy237]

Hi all , 

iv been in contact with sky Ireland in regards to the use of 3rd party router and sadly will not help, iv searched this forum to highlight some settings advice iv tried and failed . In the past iv used fttp with pppoe witch worked flawless , now that iv changed to sky its been try and errors . Sky has advised me that they use hdcp settings auto settings does not recognise sky at all I know  ipv4/6 is needed  and the

Prefix Delegation Size is 56 , some of the settings I can get from sky router but it's to copy them over to UniFi that I keep trying am I missing something in the settings ?
