Good morning.
I setup a zabbix server. It's zabbix server 7.0 on Raspberry Pi 4 with the latest Raspberry Pi OS Lite. Because the network I want to use the zabbix server is airgapped I set it up in a open network with internet and then changed the IP of the Raspberry Pi to a static from the new network and assigned that new IP in /etc/zabbix/web/zabbix.conf.php. I have access to the web gui on http://host_ip/zabbix. After that, just for a test, I went to Discovery-->Create Discovery Rule and created the Add_Hosts rule with Discovery by Server, IP Range (my range) Interval 1h, Checks: ICMP Ping allow redirected, and everything else default choices. Then I went to Alerts --> Actions --> Discovery Actions and created the Add_New_Hosts action with type of calculation : AND, Condition A : Host IP equals: my-iprange, Condition B: Discovery Rule Equals Add_Hosts and then Operations : Add Host. When I did the exact same actions on the network where I setup the server it work and found all of my network machines. But After the IP change this auto discovery is not finding any of the network hosts.
