Nagios Support Forum

I should have understood from the beginning... We have multiple external IP:s and multiple routes out, depending on which net we are on. The net we use for client surfing etc has a different route from our DMZ, where our Fusion server is. Consequently, the rather permissive firewall rules for the cl...

Tried again, with another server.
Again, NAT works perfectly in client browser, but Fusion can't reach the Nagios Core web interface.

It works. Given that the previous configuration had no problems in a web browser, there must be something...

I need to NAT because port 80 is already in use on another server and I have only one external IP address. Change to /nagios didn't work - page not found. The URL from the screenshot...

The fused server does not use SSL.
/etc/hosts are untouched for both Fusion and fused server. The problem server is added by IP, not by FQDN, so /etc/hosts is not involved.
Fused server settings are attached.

Hello. My Fusion handles four Nagios Core servers. Three of them shows without problems. The fourth shows as "Unable to retrieve the data from the local cache" in Tactical Overview, and as "Unresponsive" in Fused Server Credentials. Credentials are correct, and the link from the ...
