	i didn't even think of gui, doh! The cipe device appears as a
first selection under "add device". we'll see. first a bike ride and then
work. will report.
	one additional question: how silly would it be to have single
piece of equipment serving as both k12 and cipe vpn device for a small
group of users. the network is T1 terminated by cisco 2170, natted with
passthrough from public to private addresses.
