Oh, OK. Such a thing hasn't occurred to us, so it's not possible. In
that case I expect you'll need to stay on 5.x for now, with separate
processes for dns64 and non-dns64 (but they can share the cache).
Overall I don't think the current code can support multiple certificates.

New subject: KNOT sharing cache or not for different instances (nat64 vs no nat64)
Thank you for all your insight.
I have tested with one certificate that includes the separate dns64 domain as an
alternative name, and it works fine.
It is simpler and just requires a unique certificate for dns64 and non dns64 for DoT and
DoH.
So I will set that change in production first, and then I will be able to test version 6.x

Hello,
After simplifying to only one certificate for DoH and DoT (with an alt name for the dns64
domain), we were able to migrate to version 6.x with a single shared configuration, and it
works quite well. It is a lot cleaner and clearer as well and the dst-subnet option in
views is very useful :)
We experienced a little bug with subnets in views though.
With this type of configuration:
(…)
dns64: true
views:
- subnets: ['0.0.0.0/0', '::/0']
answer: refused
- subnets: ['127.0.0.0/8', (more IPv4 subnets)]
answer: allow
options:
dns64: false
- subnets: ['::1/128', '2001:0db0::/31']
dst-subnet: 2001:0123:53::1
answer: allow
options:
dns64: false
- subnets: ['::1/128', '2001:0db0::/31']
dst-subnet: 2001:0123:53::64
answer: allow
(…)
All queries received on a correct dst-subnet and sent from the subnet 2001:0db0::/31 were
refused when they should have been allowed!
However, we got this to work by splitting the /31 into two /32 in the config file:
(…)
dns64: true
views:
- subnets: ['0.0.0.0/0', '::/0']
answer: refused
- subnets: ['127.0.0.0/8', (more IPv4 subnets)]
answer: allow
options:
dns64: false
- subnets: ['::1/128', '2001:0db0::/32’, '2001:0db1::/32']
dst-subnet: 2001:0123:53::1
answer: allow
options:
dns64: false
- subnets: ['::1/128', '2001:0db0::/32’, '2001:0db1::/32']
dst-subnet: 2001:0123:53::64
answer: allow
(…)
Regards,

Thanks a lot, that really is a bad bug of mine. I think it is fixed in
this MR already, but I want to spend more time on it still:
