It's a standard cable modem & router (Netgear).  The cubietruck is
connected directly to the modem.  I'm issuing the HTTP from a laptop,
and both a wireless and wired connection gives the same behaviour.

I was planning on capturing some traffic from a third system to see
what's actually on the network, but I don't think I'll find the time
