Nagios Support Forum

Hi,

If Nagios xi is installed in one location (let's say vlan 1), is it possible somehow to access it remotely from vlan 2, or just from a different geographical location?

Also, if Nagios is installed on a physical server, it can be accessed via browser (Windows PC) only if it's in the same network?

Thanks!

Hi flender,

It is going to depend upon your network configuration but it should be possible. VLANS operate at layer 2 of the OSI model while SSH operates at layer 4 on the stack. In between these two layers is layer 3 ( IP ) which is key to whether or not you can connect. If there is IP connectivity ( a route ) between the two systems and no filters in place the connection at layer 4 should be possible.

Said more plainly if there is a route between the two systems and no filters blocking TCP port 22 it should be possible to SSH into the system regardless of geography. The same thing applies to accessing the Nagios xi interface if there is a route ( IP layer 3 ) and no filters blocking ports 80 and 443 you should be able to access it locally or remotely.

You'll have to work with your network team and/or server provider to ensure that you have this connectivity. Hope this is useful.
