Routing a IP on ARMBIAN 23.8


I am using a ROCKPI E.

I switchted my OS from Ubutnu to ARMBIAN 23.8 Bookworm. I am still confused, if this was a good idea. I read that ARMBIAN should be the “better” OS for the KERNEL. Is there a rule of thumb what to use?

On my Ubuntu i made some settings to route my IPS, since i am controling a pump on ETH0 and using my LAN on ETH1. On UBUNTU i made this changes on dhcpcd.conf:

interface eth0
static ip_address=
static router=
static domain_name_server=

Since this file does not exist on ARMBIAN, where do i make the changes for this on ARMBIAN?

thank you
