Hi -
I changed router to a DrayTek Vigor2862 - and now my BT Sport is not working, reporting an IPC6023 error. I've tried going through all the steps recommended (restarting router, re-booting TV Box with factory settings etc). IGMP Proxy and IGMP Snooping are all enabled. Have tried accessing the link below, but it says I do not have permissions. Can someone please help?

You'd be better off searching for IPC6023 Draytek in the search bar above
