[dnsdist] How to pass source IP to the next DNS (Adguard Home)

[Michel Otte]

Hi Alexis,

I'm not sure if your comment concerns the dnsdist side or Adguard Home
side, but dnsdist is not targeted specifically to home use. That does not
mean it cannot be used in such a scenario. Having said that, from the
dnsdist perspective it is only a matter of one extra configuration
parameter. I'm not sure how that translates to "quite some work", but maybe
dnsdist is not the right tool for your job then.

With kind regards,
Michel Otte

Thank you Michel
