Does Zabbix require a stateful connection, or can it get information passively? I've been reading the documentation a bit, and I am scratching my head. 

Lets say that I have customer environment "A" and my environment "B". Due to PCI compliance, I need hosts with a Zabbix Agent to connect to env B, and send information to the Zabbix Server located in Env B, without allowing the Zabbix Master in Env B to contact the Zabbix Agent directly in env A





I can see that the proxy allows a one way tcp connection, but I want to be sure if it is client initiated or not.

Is this possible to use in this way?
