Nagios Support Forum

Sorry its me again, I have monitoring some devices with nagios connected in one switch, all devices and my server is in the same network, but i need to disable the firewall in the ubunu server (where i have nagios) to enter to the web interface.

Another issue is that i have monitoring windows server in virtual box, all services its okay, but the PING service doesnt work, and reality i cant ping to the win server physically, this is when the firewall of winserver is on, when is off the PING service is up and i can ping, Do i need to cofigure the ports of winservers to ping with the firewall on and the nagios server to enter to the web interface with the firewall on too?

Here is a link for changing the firewall settings on your ubuntu server.
https://help.ubuntu.com/community/UFW
Your windows server, we will need to know which version you are running in that to allow ICMP inbound.

Im using WS 2012, how to allow ICMP?, finding i look that it protocol doesnt have port

Try this link for Windows 2012 server ICMP inbound rule for your firewall.

Thanks, it works, it needed to allow the protocol not a port in specific, duh xD.

So, the problem with accessing to the nagios web interface without the ufw disable, how i can enter with my nagios server firewall enabled?

Try running this to allow http and https through the firewall.

It works, its secure to allow these ports right?

Yes

Very thanks!, can close this trhead
