<html> <head> <style></style> </head> <body class='hmmessage'> Hello!<br><br>I'm fairly new to nagios, and im hoping that someone of you have had a similiar situation which i am currently facing.<br>The active servers i got on my local network is being monitored fine, with all the services i have written.<br><br>BUT, how do i monitor a server BEHIND a firewall? can i filter on ports on the firewall to accept active checks from nagios, or can i walk around the problem by configuring pasive checks? Meaning klient -> server, instead of server -> klient.<br>Ive read that this particular option is when i want to use NSCA, which im trying to get to work, but so far no success. I do want some kind of client-agent that sends out notifications to my nagios server, but at this point, i havn't got anything to work...<br><br>Could someone please help me out? Is nsca the best option? Or are there other choices?<br> </body> </html>
