i have 4 Ubuntu 20.04 VMs running on VirtualBox. Each Ubuntu has 4 network adapters which i have added, they are all in bridged connection. My goal with this ideea is to have different networks such as (10.1.1.10/24 or 220.127.116.11/24 ore 18.104.22.168/24) on each interface so that VM(1,2,3,4) has 3 networks on each interface (leaving the first interface alone because of connection issues). And if i try to ping lets say interface3 from VM2 which has the network(22.214.171.124) from vm1 interface 2 which has the network(126.96.36.199) they should not communicate but they do. My goal is so that i can clearly see that if they are not from the same network , they shouldnt ping each other. But at the moment , whatever ip address i give to the interfaces they all communicate with each other.
