Allow pass-through of ECS from client to upstream server #166

Open timkgh opened 3 years ago

timkgh commented 3 years ago

In some cases clients send DNS requests with ECS (e.g. dnsmasq behind dnsproxy can send ECS via --add-subnet). But it does not seem to be passed upstream by dnsproxy, or at least I can't get it to work.

Can you please add a config option --edns-pass-to-upstream? The logic should probably be: if client supplies it, pass it through. If the client doesn't supply it and --edns or --ends-addr are enabled, use those.

It can be tested like this: dig o-o.myaddr.google.com txt +subnet='1.2.3.0/24' @8.8.8.8 (replace 8.8.8.8 with the address of dnsproxy)

Has this been implemented? Or expected version in which this may be implemented...

Any update?

No updates yet, we didn't have time to implement dnsproxy feature requests yet.
