Polling over second network interface

I need to monitor some devices on a separate part of our network. I have setup a second network interface attached to the other network. From CLI I can ping out to the network just fine but LibreNMS won’t connect to anything on the second network. Can LibreNMS work over multiple networks like this and if so, how do I make this work?

It shouldn’t care about the networks so long as your network is setup ok and routing correctly.

If you add a device by hostname and it points to and that IP is on the second nic then it will go through that nic if all is setup ok. Short is, it’s unlikely to be a LibreNMS issue.

After some more digging, it looks like the problem was with the SNMP community string. whoever set up the device did not user our standard one. Thanks anyway.
