Before you install proxy, keep in mind that your proxy version must match the Zabbix server version!

Understanding Zabbix proxy Active vs Passive mod
When you use a proxy in active mode, it will connect to the Zabbix server to retrieve configuration and send data. This is a great feature that enables active proxy server to work behind a firewall.
And if you use a proxy in passive mode Zabbix server will initiate a connection to the proxy to send configuration and retrieve data from the proxy.
Before, in this tutorial, we have configured proxy server to work in active mode. Let me show you how can you configure the proxy to work in passive mode.
Open file zabbix_proxy.conf with the command: “sudo nano /etc/zabbix/zabbix_proxy.conf” and turn on passive mode and define Zabbix server IP address by adding this anywhere in the file (change “Server” parameter to to match your Zabbix server):
ProxyMode=1
Server=10.7.44.235
