I am trying to help my brother replace his BT HH6 with something else....challenge is he wants to set Umbrella / Open DNS for home DNS server but BT HH6 does not allow that to be changed 

We are also trying to ensure he ends up with a router that works with BT IPv6 service...at the moment he uses Google WiFi Mesh for APs so WiFi is not that important although we have also been struggling with making v6 work across that as well 

I have read that TP Link sells VDSL routers that will work with BT Infinity 2 service but wanted some suggestions ?

I believe all we will need in terms of seetings from BT are the PPPoE credentials ? Is that correct ?

Thanks in anticipation ?
