v6.2.2 broke conditional forwarding

[GustelDE]

Hello,

with the latest update to v6.2.2 broke my conditional forwarding.
I set up:

sudo nano /etc/dnsmasq.d/02-custom.conf

server=/lan/10.88.101.51
server=/88.10.in-addr.arpa/10.88.101.51

Which means all ".lan"-zone-requests are redirected to the DNS-server 10.88.101.51. This worked until v6.2.1
But with 6.2.2 it logs "nameserver 10.88.101.51 refused to do a recursive query".

I configured 10.88.101.51 to allow recurisve querys, but no change.
I rolled everything back to v6.2.1 and everythings works again.

Can anyone provide me with some help.
Thanks

We did just release FTL v6.3.2 so you may want to double-check the versions you mentioned here. Anyway - there should have been no intended change to this. What changed indeed is that the warning is shown since FTL v6.3.0 because displaying it was broken before. So nothing more than cosmetics should have changed.

Could you provide relevant lines from your /var/log/pihole/pihole.log from the version where you see this broken?

Hi, sorry, I mean FTLv6.3.2
I tested again and it is reproducible.

I think it is 100% related to this release.

[GustelDE]

I think I found the issue, I had under Settings -> DNS -> DNS domain settings
"lan" definded:

After deleting "lan" (empty box), it seems the resolution works with v6.3.3.
But with v6.2.2 everything worked with exactly this config.

[DL6ER]

Sorry for the delay in replying. With FTL v6.3, the setting dns.domain was migrated to dns.domain.name. When you didn't have dns.domain set (= empty value) the migration has a known flaw and you ended up with the value being resetted to the default value dns.domain.name = "lan" which is probably what was affecting you.

Sorry ...
