Zabbix server not getting data from Windows Agents

[bigalnz]

I have a server on my home lab on VMWare and it does not seem to get any data from the agent in passive mode.

ENVIROMENT:

Server Zabbix 6.4.2
Server IP 192.168.110.104
Zabbix Server running on VMWare ESXi 8

Between the server and physical hosts is Fortigate FG60E firewall. Zabbix is on LAN3 interface for wired hosts - LAN2 is for wireless hosts (different subnets)

HOST1

Windows 10 Laptop
Zabbix Agent 2
Windows Laptop IP 192.168.200.102

HOST2

VMWare Windows 10
Zabbix Agent 2
VMWare Windows 10 IP 192.168.200.106

Steps taken so far:

1. Windows firewall down on both VMWare windows 10 and laptop Windows 10
2. All computers (hosts and server) can ping each other

The issue seems to be confined to hosts that need to cross the subnets.

There is no NAT between subnets and if I inspect intercepted pings on the FG60 I confirm no NAT'ing.

I did a packet capture on the FG60 for traffic between server and Windows Laptop host (port filtered 10050and there is nothing but some broadcast stuff)





Suggestions?

Enable the debug logs in agent and see what happen.
