Adding devices from a secondary NIC

Question about multiple NICs on LibreNMS.

I’m running LibreNMS on a virtual server with multiple NIC’s. When testing, I initially had my primary NIC as an internal IP address A.A.A.A and was able to add any type of device on this subnet. Secondly, I added B.B.B.B as my primary NIC and A.A.A.A as my secondary. I can add anything on my B subnet but can no longer detect or add devices on my A subnet. I can only add devices as ping only.

Is this possibly an ip route issue?


Yeah you need to configure your Linux for this work… this is really not a LibreNMS issue.
