Do I need to change my PI settings or router settings?

    So I have a QNAP NAS, and for some reason I have noticed recently that on occasion my Pi keep changing IP addresses. And when it does, I have to take that new IP address and add it into my NAS settings for it to see the multimedia. Is there something I should be changing on the PI to prevent this from happening, or is this something I need to fix in my EERO router? Granted I haven't changed any router or PI settings, but it appears to happen more frequently than before.

    If you are granting access to NAS shares only to specific IP's and the RPi moves around the DHCP scope, you could:

    • Configure a static address in the RPi and then allow that address on the NAS
    • Create a DHCP reservation in the router for the RPi so it is always dynamically assigned the same address
    • Create credentials to access the shares and avoid the need for IP blocking

    IMHO using a DHCP reservation (makes SSH access to the RPi consistent) and also using credentials and basic access controls to manage access to shares is the winning combination. From a security perspective IP blocking is a fairly blunt instrument.
