zabbix_sender connect to trapper port < 1024

[nstaelen]

Hi all,

We have a setup in which we use active agents in combination with a zabbix server in the cloud. Zabbix is configured (by default) to accept connections on incoming port 10051. However, in order to circumvent firewall exceptions on the client side, we've enabled port forwarding on our zabbix server so that all traffic on port 80 is forwarded to port 10051. Hence, the active agent can connect over port 80 to the zabbix server. This setups works and the (active) agent is able to communicate the active checks.

Next to the active checks, we have also some zabbix trapper items defined. From time to time, data is pushed to the server by using zabbix_sender. If we configure zabbix_sender to connect to port 10051, we are able to successfully send the data to the trapper item.
However, when we try to connect to port 80 using zabbix_sender, the following error message is displayed:

zabbix_sender.exe [9708]: Warning: Incorrect port number [80]. Allowed [1024:65535]
Sending failed.

Are there any suggestions on how to allow zabbix_sender to connect to port 80? Or other alternatives to push data to be catched by the configured trapper items?


Thanks

Hi,

I'm afraid that this is not possible. The only thing I see would be forwarding the trapper port to 80 somewhere in the firewall if possible.
