Hello Everyone,
First, an explaination of the network. Zabbix is located in a DMZ that has absolutely no access to the internal network. The internal network does have access to the DMZ through access control lists on the firewall. Here is the problem:
I have the agent in Active mode. The agent is reaching the server, but for some reason the server is not getting any information from the agent. I can follow the traffic and see that it is getting through the firewalls fine (tcp port 10051). All of the hosts on the DMZ the Zabbix server has no issue with. From what I understand, the agent initiates the tcp connection, and closes it. The Server doesn't need to initiate any communication with the agent.
Any ideas?
tl:dr - I need the internal network hosts to connect to the Zabbix server in the DMZ without the Server initiating any connections.
