  • Sometimes even that’s not enough. I’ve had some questionable kit before that would just ignore the DNS settings fed to it if it thought they were no good, and fall back to something else preconfigured.

    pfSense is a wonderful tool for situations like that. Anything intended for local use only here just doesn’t get outside at all. Handy for stuff like a fire stick that only needs to be calling up a local media library.

    It can also mangle any DNS requests going out to a different server and redirect them to itself instead. You could do this without it with iptables/nftables on a generic Linux box, but pfSense makes it much friendlier.

    There are other packages that can do the same, but physically all you need is one piece of hardware as a bouncer that manages connections between inside/outside.




  • On Dell server hardware with the right cards/licensing, you can remove the need for physical access to the server to input an FDE password by leaning on iDRAC. This provides access to the console remotely during the boot process (and thereafter).

    Alternatives exist that supposedly do the same thing, but I’ve never had to try them. Airconsole, pikvm, blikvm etc.

    You can keep this interface unexposed by using wireguard to dial in when you’re away, as per your original thinking. Just make sure the endpoint isn’t on the server you’re rebooting…
