I can get manual ip’s on the interfaces manually, but need to read the docs to automate it on boot…
My setup is using dnsmasq and its working after I set the interfaces up, and I get a DHCP on a test system.
Most of my setup is default, this is what I do at the moment. Note I am using Armbian:
#Setup on the network is below. I then run
ip link set lan1 up
#Then restart dnsmasq to git a DHCP ip on my test system.
systemctl restart dnsmasq
