Multiple NICs for plant network (internet) and PLC VM network

Hopefully someone who is good with networks and VMs can help me out.

I have several VMs on this server. The only one really being used is the ignition production VM.

We use the plant network NIC to access perspective from multiple computers in plant on local network.

I now need internet for a 3rd party module. When I add the gateway 10.30.0.254 to the plant NIC and disable the 192.168.200.25 on the other NIC my module works, but PLCs lose access, even though I can ping them. See attachments.

Before i started this the plant gateway address was not on the plant NIC, and we could access perspective through IP address. We still can, but internet does not work unless I disable 192.168.200.25.



So, the PLCs that would be reachable via the local network do not have addresses in that same subnet? (192.168.200,.0/24) But need to route through 192.168.200.1 ?

If so, you will need to use advanced settings to add static routes to those subnets via 192.168.200.1 (instead of using the gateway field for the NIC).
