How do I proxy DNS requests from bind9 to acme-dns?
Here is my named/bind9 configuration file
options {
directory "/var/cache/bind";
auth-nxdomain no; # conform to RFC1035
dnssec-validation auto;
listen-on-v6 { any; };
dump-file "data/cache_dump.db";
statistics-file "data/named_stats.txt";
memstatistics-file "data/named_mem_stats.txt";
recursion yes;
allow-recursion { any;}; # had to change to allow bind9 to query 127.0.0.53
version "go away";
};
zone "xample.in" {
type master;
file "/usr/local/etc/bind/zones/db.xample.in";
};
zone "auth.example.com" {
type static-stub;
server-addresses { 127.0.0.3; };
forward first;
forwarders { 127.0.0.3; };
};
I setup acme-dns to run on 127.0.0.3:53. it replies to SOA, NS and TXT records.
While querying with dig TXT test.auth.example.com +trace, I see -E(0)D which can be reproduced with dig TXT test.auth.example.com @127.0.0.1 +norecurse +noedns +dnssec

I tried setting dnssec-validation no;, it did not work
