    * Deployed the peer testing implementation to be run every few minutes on
      each router, as well as any time the user requests a test manually.  The
      tests do not reconfigure the ports at the moment, merely determine under
      what conditions the local router is reachable.  The status shown in the
      top left will be "ERR-SymmetricNAT" if the user's IP and port show up
      differently for different peers, "ERR-Reject" if the router cannot
      receive unsolicited packets or the peer helping test could not find a
      collaborator, "Unknown" if the test has not been run or the test
      participants were unreachable, or "OK" if the router can receive
      unsolicited connections and those connections use the same IP and port.
