How to close a subnet for a network card?

Question

Computer networks

Essence of a question: on the PC there are 2 network interface cards. The subnet I need 192.168.10.* is present on 2 network connections (in 2 networks), respectively, the devices in these 2 networks are different and I would like to make sure that one network (automatic IP) does not have access to this subnet, but that the second network (stat IP 192.168.10.155) worked freely with it.
Tell me how to do it?

Answer 1

Set the subnet mask /32 on the interface of the first card and add the route 192.168.10.0/24 through the second one. But this is a crutch - you should not do the same ranges on several interfaces at all.
