    We use dns clusters but it seems the dns can resolve for anyone that uses it.

    Does anyone know how to secure the dns remote servers so they will work only in our network?

    Thanks,

    Charles

    Hello :)

    Could you provide an example of the behavior you notice so we may have a better idea of the exact issue?

    Thank you.

    Sure let me try to explain. In my local laptop I can add my dns servers to the internet connection and it will use my dns servers to resolve all my dns.

    I would like to protect my cpanel remote dns servers to only be able to resolve my network only, not just anyone that puts our dns IP's in their system.

    I would like to limit it to a set of IP's

    If you need to secure your DNS server so that only certain IP Ranges can get to them, you either need to configure this on a hardware firewall infront of your DNS server or use IP tables on the server.

    This way you can create a rule that says that only IP's from x/24 will get access.

    Hope this helps :)

    Thanks, my questions is if I limit this in the firewall then can people still access the domains being resolved by the server the same.

    Obviously I want me servers to resolve through the dns servers but if I block the rest of the world can that block any access from regular surfers when viewing a domain in my network.
