Modify NAT subent on bare-metal

[mareox]

Hello Eve team,

I am using EVE-NG Pro on a bare-metal server and I would like to change the NAT subnet.
I can't find the instruction in the documentation/cookbook.
I have tried changing the subnet in the /etc/network/interfaces file, upon changing the interface I rebooted the machine, but it doesn't take effect when adding a NAT interface in the lab.

Can you please point me in the right direction?

Thanks,
