Zabbix 6.4 error monitoring subnet

[jasuarezh]

Hello

I have the zabbix server in a subnet 192.168.0.X in this subnet all the zabbix agent that I have connect well without problems. I have another subnet 192.168.2.X with that subnet I have problems to connect the zabbix agent to the server. In the log of the zabbix agent we have that error "failed to accept an incoming connection: connection from "192.168.2.254" rejected, allowed hosts: "192.168.0.106""



IP: 192.168.2.254 => gateway
IP: 192.168.0.106 => Zabbix server

And in the zabbix server we have that error



In this moment I don't use TLS connection

I check the communication between zabbix server and zabbix agent and I have connection by ping and telnet in port 10050 and 10051

Anybody has this problem?

Thank you

Hi,
Seems like the Zabbix agent is configured to accept connections only from the 192.168.0.106 (Zabbix server), but it doesn't accept connections from the gateway 192.168.2.254.
Could you please check your zabbix agent config?

It should look like this:
Server=192.168.0.106,192.168.2.254
ServerActive=192.168.0.106

Hi kamil1,

Thank you for your answer, with that zabbix agent connect to the server without problems

Thank you very much

Why that incoming connection even has IP of gateway? Some bizarre translation in play?
