Hello, I want to monitor a linux server, like I do with with all my other linux servers.
Only difference is, that this linux server is in a dmz.
Inbound to dmz everything is allowed, but outbound I only allow port 5665.
The first configuration works with no errors, but all the director shows “Remote Icinga instance ‘Client’ is not connected to ‘Master’”.
I tested telnet to the master port 5665 and it works, I also testet telnet port 5665 to the client, also works.
Is there a second port I need to allow in order to get this working?
Log looks like this:

I already reinstalled the icinga agent on the client, this exact configuration works on all other clients, only difference is the dmz.
Thanks for advice.
