Why is the Device unreachable?
I have several sites (55); all with different subnets (10.xx.) or on different Public IP addresses. Still I can monitor them all from my Orion system.
I think this post may need to be moved, as I don't believe it relates to Alert Central.
Is there something about Alert Central that you're curious about?
Are you asking if Alert Central can process the alerts/e-mails generated?
Thanks in advance!
