I can not change the MAC address for the IPv6 router...

That needs a bit of explaining. My ISP, Ziggo, only provides native IPv6 to non 
bussines accounts with a very limited set of modem/routers. These modem/routers 
do not allow changing the MAC address.

I can have the modem set in bridge mode and use my own router. Then I can 
change the WAN MAC address. But with the modem/router in bridge mode, I only 
have IP4.


Cheers, Michiel
