This should work unchanged. Uml uses TAP devices (tuntap is actually TUN/TAP,
and we use TAP, which means we pass down even the Ethernet frame). More
important, the interfaces are called tap#.

What the hell are you doing above? I see some routing setup done on ppp*
interfaces (does this relates with ethertap at all? I don't know how).

Go to the "Virtual Networking" page on the website, it's all explained there.
