I have two virual machines on Virtualbox.

In the first one I installed Ubuntu and inside the Ubuntu I installed OVS and created a mininet (4 hosts).

In another VM I installed Kali Linux.

From hosts in mininet (for example h1), I can ping google.com and can ping the Kali Linux machine.

But from the Kali Linux machine, I cannot ping h1 ( I think because I cannot reach their IPs from external hosts)

h1 IP = 10.0.0.1

h2 IP = 10.0.0.2

h3 IP = 10.0.0.3

h4 IP = 10.0.0.4

I think the solution is something like this:

*The OVS switch is configured to function as L3 switching

by combining the OVS software with Linux kernel routing.

In this case, all the virtual hosts can communicate with each

other using different subnets*

But I don't know how to do it

Many thanks
