I'm new to OpenWrt. I've got it running on a Raspberry Pi with a Wan and Lan interface. DHCP isn't working and it sounds like I need DHCP Server running on my Wan interface and DHCP client running on my Lan interface. When I change the Wan to Static (I have a reserved IP on my Google Fiber Router and it is marked as a DMZ to allow outside traffic), it changes back to DHCP when I reboot.
Is there a comprehensive getting started guide for OpenWrt NEWBIES for setting up OpenWrt at home with DHCP Server (or passthrough to router) and a couple of VLANs? I've got a Kubernetes lab running on six Raspberry Pis and I want to put them on one private subnet and then I want a second subnet with a bastion host. I haven't figured out how to allow Ingress to the private subnet. I am running https://github.com/inlets/inlets-pro/, so I think I can use tunneling for all ingress.
