Server "flapping" question

[jimhoffmann]

I am evaluating Nagios XI and ran the auto-discovery to add most of the servers in the environment to Nagios for monitoring. I also used the monitoring wizard to add several servers in a DMZ. Nagios is indicating these servers are all "flapping" however, I see no issues when pinging these servers from a 'root' login on the Nagios server. Any ideas?
Thanks!

What is the output on the Service Detail Page?

I have resolved the issue - the firewall was causing the server to appear to be "flapping".

Thanks!
