Hi Double check out the zabbix manual but I believe SourceIP is the network card the server uses as its outgoing address. In this case you have 127.0.0.1 which won't go anywhere. Try adding the card of the 192.168.1 network instead. Hope that helps Michael On Jan 21, 2014 7:32 AM, "John McIntyre" <joh...@gm...> wrote: > Hi, > I'm having issues with zabbix, the server of which can't connect to an > agent.
