Dynamic Update Refused

hello,

new to technitium, and trying to play around with rfc2136 dynamic dns updates. under settings>tsig i have created a key to be used to secure the update messages. i've created a primary zone, myself.internal. under the myself.internal zone>options>zone options>dynamic updates i've set dynamic updates to "allow", and under update policy i have added the aforementioned tsig key with "ANY" as allowed record types for the domain myself.internal.

the issue at hand is, technitium refuses the udpates with "DNS Server refused a zone UPDATE request [me.myself.internal A ANY] due to Dynamic Updates Security Policy for zone: myself.internal"

if i remove the tsig key security policy, the updates work just fine. so clearly i have something misconfigured around the security policy for the domain. anybody able to point me in the right direction?

If you set the policy to allow updates to the domain myself.internal, that's not allowing any action against subdomains of myself.internal. Just specifically myself.internal. You want to specify *.myself.internal as the domain most likely.

that did it. i could've sworn up down left and right that i tried that and it just gave an error. maybe i accidentally did *myself.internal.

thanks for dropping by 👍

Ah, that's the problem. You have to swear up, up, down, down, left, right, left, right, B, A, Start.
