Zabbix Proxy to Zabbix Server

[stevefxp]

Hello all,

I have a Zabbix proxy and main Zabbix server, separated by a VPN connection. I can ping each from the other side with no issues. I can also setup a passive connection from the proxy to server. When I change it to an active connection it fails.

Is there something to getting an active connection over a VPN? Is there something different between passive and active connections that i am missing?

Thanks,
Steve

Check Firewall and ports:

Passive Mode
ZaabixServerIP --> vpn --> ZabbixProxyIP:10051

Active Mode:
ZabbixProxyIP --> von --> ZabbixServerIP:10051

And the mode must be set to:
proxy conf file

https://www.zabbix.com/documentation/6.4/en/manual/appendix/config/zabbix_proxy#proxymode

and in Administration --> Proxy

So I checked the ports and it seems 10050 is open both ways but 10051 is not open either way. Now I do not set anything in the firewall about these ports, so why would 10050 be open and 10051 not be open. That is the new question.

Ok so I cleaned a few things up...

Let me provide some additional information on my setup. I have site A and Site B, which are connected via a VPN connection. Site A has the main Zabbix server and site B has a Zabbix proxy and other devices reporting to the proxy. The Zabbix proxy also has a Zabbix agent, so its doing double duty. I have tested connecting to the Zabbix main server from the proxy, by port(10050/10051) and pinged the main server by FQDN. All come up successful. When I setup communications from the proxy to the main server I can do so in passive mode. When I change to active mode it fails saying that cannot send proxy data to server at "FQDN": proxy "FQDN" not found. I double checked the proxy settings on the main Zabbix server and its set to the FQDN of the proxy and set to active.

I really do not know if/what I am doing wrong. Anyone got a thought on this?
