I have solid experience configuring and maintaining Linux, but my knowledge in networking is quite basic. What should my first configurations and preparations should I do before flashing Openwrt and setting it up for my home network?

PS. If I can use the switch as a NAS, I'd be delighted.

Thank you for all the questions to help me clarify my use case 🙂

At the very basic, I'd like to:

achieve better security through segmentation by isolating cloud-connected devices, guest devices from trusted devices.
Being able to "pin" a Mac address to an IP, and being able to use internal network name resolution to reach those devices.
a blocklist for known ad-domains / malicious domains.

Once the basics are in place, I'd like to elevate my netsec game and implement:

a high level monitoring capability to seen what devices are communicating with what domains / IPs
An IDS capability of some sort to be able to detect anomalies in my LAN.

The NAS part is just for convince, it would be nice to have a samba / NFS with my files available when I need them.
