Hi everyone,

I have a Synology NAS and a lot of computers in our network connect to it with its public url and we have had some outages of internet recently which made me think of some things.

Basically what I want is that if the DSM domain https://dsm.example.com isn’t reachable it will resolve its local IP https://192.168.1.200. This should be a rule for the whole network and not only manual change on every computer.

I have a lot of dockers running on the DSM which of course are still directly reachable but for example bitwarden is setup with the public address as it needs to sync everywhere.

Ideally this would be like you put in primary and secondary DNS in the modem. So if one isn’t available the second one is picked.

Any help in the right direction of how this can be done, or how this is called is welcome.

    I have Adguard running and setup as primary DNS in the modem. So u/Accomplished-Moose50 just named Adguard already as an option to do “magic” there.

    Aaaah, I think I get it. So in Adguard there is just the rule to always forward any request to example.com to 192.168.1.200 because that is always true.

    Yes that would work! Just have to find out how ^^, I’ll dive into the documentation of adguard.
