setting mtu on stf0

I have a mac osx server acting as router/firewall for my home network. The interface (I assume created by setup assistant for connection sharing), stf0: has an MTU 1280 and I need to increase this. I tried:

sudo ifconfig stf0 mtu 1364
but it fails with ioctl set mtu: invalid argument.
(The same command can be used to set mtu on the other interfaces)

Does anyone know how I can increase mtu on stf0 ?
