But another problem has occurred: signal from the monitoring server reaches the nodes, but the one from the nodes doesn't reach the server.
+/var/log/messages is absent.

Are you trying to see if the NRPE Agent is running on the Nagios server from another server?
Can you describe what you ran, from which server and the error message you are receiving?

This is what I got.
In monitor server (ip - 192.168.1.1) In remote server (ip - 192.168.1.2)

Your screenshots did not post. Could you try attaching/posting them again please?

And now?
By the way, maksibonus is my friend and we together are trying to solve this problem.

From your screenshots we can determine that the remote server 192.168.1.2 cannot talk to the monitor server 192.168.1.1 (however the monitoring server can talk to itself AND the remote server).

Do you want the remote server to be able to query the monitoring server?

Normally the traffic direction is:
Monitoring Server > Remote server.

The remote server responds back on that same connection, it doesn't need to establish another connection in the reverse direction.

There's been a few issues brought up in the past forum replies. What is your current problem and what is the goal you are trying to achieve?

I split this topic as the new problem is unrelated
