OK, Return path not tested (green
checkmark)
Displayed for a device, which is reachable but which does not support the
feature to test the return path (device sending to this L-IP). Therefore a potential
NAT router configuration error cannot be detected. If the tested device is an
L-IP it is recommended to upgrade this L-IP to the most recent firmware.
Not reachable/not supported
(red exclamation)
Displayed for the CS if it is not reachable or the CS does not support this test.
To remove this uncertainty it is recommended to upgrade the the most recent
firmware.
Local NAT config. Error
(red exclamation)
Displayed, if the L-IP is located behind a NAT router and the port-forwarding
for the L-IP in the NAT-Router (usually 1628) is incorrect.
Peer not reachable
(red exclamation)
Displayed for a device, if it is not reachable. No RTT is displayed. The device is
either not online, not connected to the network, has no IP address, or is not
reachable behind the NAT router. Execute this test on the suspicious device to
determine any NAT configuration problem.
