Whitelist dynamic IP

[Cilenco]

Let me first say that I love AdGuard, it is such an amazing production, thanks so much for the whole development team!

A feature I would like to see is an addition to the whitelisting of clients. I have deployed my AdGuard in the cloud. My FritzBox is sitting behind a DSLite tunnel but with a MyFritz account I have a dynamic IP which always points to my router. I would like to restrict the access to my AdGuard only to my router so it would be great if I could whitelist the dynamic IP otherwise my DNS queries will not get resolved when my IP changes.

Would something like this be possible in the future? Currently I have written a script which updates my IP through the AdGuard REST api (pointed my DynDns endpoint to that script) but it would be nice to have this functionality directly build into AdGuard.
