I am able to reach both, one thing I am noticing is that these are both 
3.1.2.  I would suggest upgrading to 3.2 if at all possible.

In any event, report back if you are seeing data when you get a chance - 
also if you suspect a firewall may be an issue, try some simple tests to 
some of the hosts that are in the regular testing groupings, e.g.:

  owping HOST_IN_LATENCY_TESTS
  bwctl -c HOST_IN_BW_TESTS
  bwctl -s HOST_IN_BW_TESTS

If these fail for any of the hosts, firewalls may be an issue.

Thanks;
