changes to the VPN setup? What tests are showing red/flapping? Are all tests for these affected hosts red/flapping? You say it is only those systems with a private network, do you have others that aren't a private network through the same VPN that are OK? What
is happening at the VPN gateways at each end, can you run tcpdump on these systems to find any patterns? If tests are flapping, that means some packets are getting through, you should be able to see this on the gateways.<o:p></o:p></span></font></p>
