FW:1.04WW
(Factory reset, upgrade, power off at mains for 30+ seconds, factory reset, new config)
Found another bug in FW:1.04WW all my iPv4 rules no longer work, this bug may have been there in 1.03WW as well but I hadn't checked to see that they were being enforced.
I have returned to 1.02, rules work fine using that FW, will contact dlink support Monday
