You don't have to, no. The tunnel can start from one of your hosts on the
LAN. Of course you can just as easily start the tunnel from the router.

In thoery yes. I've never done it personally. From theads I have seen on
this list it is possible, but sounds difficult.

There is little point in testing any of these features in a 6over4  tunnel
as the majority of the time your IPv6 packet is encapsulated in an IPv4
packet. Only on a IPv6 enabled device will the IPv6 headers be seen and so
adhered to.
