BT SPORT on Netgear Nighthawk

Hi 

I am new to these forums, having only just bought the product.  I am in the UK, my internet provider is Plusnet, with whom I also have a subscription to BT Sport via a Youview Humax box.  Everything is working perfectly except for the IPTV BT Sport - there is the IPC 6023 error.  

All the other internet services are fine - I have a connection via devolo power line adapters. Netflix and BBC IPlayer are working fine. I previously had to change some settings on my Asus router to get the BT Sport to work and to clear the 6023 error.

I have spoken to plusnet, who directed me to Netgear support- I have just got off the phone to an extremely rude and unhelpful Netgear tech guy, so thought I would try the community to see if anyone knows the correct router settings

thanks in advance :-D
