This is what broke the incoming NAT service for the Mode-S project.  The 
Atom computer on 172.30.0.53 has a default gateway of 172.30.0.2 which 
is supposed to be doing NAT ... UDP port 9742 from the outside is 
supposed to go to the Atom.  It looks like that Monkeybrains uplink is 
now 199.188.193.88 and I *thought* that link was provided by bikeshed in 
the past.  The uplink is working fine, but there's no NAT.
