missing config, for local nameservers

[ThomasCr]

Hi, I miss a option, to forward requests to specified domains to a local nameserver. eg. *.fritz.box or speedport.ip to my router or mydom.local to my local domain name server and also 0.0.168.192.in-addr.arpa and so on...

A workaround for this is to run Unbound as a local caching forwarder listening on port 53, configured with stub zones as you need and then forwarding all other zones to Stubby on a different port.

An Unbound config file something like the following:

   interface: 127.0.0.1
   do-not-query-localhost:  no
stub-zone:
    name: "example.com"
    stub-addr: 192.0.2.68
forward-zone:
  name: "."
    forward-addr: 127.0.0.1@8053

Combined with an updated stubby.yml that uses:

listen_addresses:
  - 127.0.0.1@8053

Should work. A more detailed description on this kind of setup will be on dnsprivacy.org soon....

For a more complete example, my configuration is: – unbound.conf

server:
  use-syslog: yes
  username: "unbound"
  directory: "/etc/unbound"
  trust-anchor-file: trusted-key.key
  root-hints: "/etc/unbound/root.hints"
  do-not-query-localhost:  no
forward-zone:
  name: "."
    forward-addr: 127.0.0.1@8053
    forward-addr: ::1@8053

– stubby.yml

I’m only using port 443 servers since port 853 is quite often blocked, while 443 is almost never (at least never encountered any case where 443 was blocked but not 853).

Thanks for this - I've used this example on the website https://dnsprivacy.org/wiki/display/DP/DNS+Privacy+Clients
