Yes, that can work, as it is just proto-41 and any Linux/*BSD box
terminates that perfectly fine (given it has 6rd support, which current
kernels most of the time have, heck it is proto-41 with special config).

Still, as I stated, it is not native and you get a MTU of 1280 and
dynamic prefix, thus for me there is no reason to change that.

Having it native would maybe change my mind though :)
