i have two mailservers in a DMZ
and now a new SUGO on YunoHost
all hosts are configured to use dns server 10.10.10.1 from the firewall
and in the firewall : Unbound DNS Overrides : all mailservers are configured:
- On A ping B response from 10.10.10.20
- On B ping A response from 10.10.10.10
- On C ping A response from public IP A
- On C ping B response from public IP B
how can i configure YunoHost to use the firewalls DNS?
thanks in advance
I change the /etc/resolv.dnsmasq.conf and add a line on top of the file
Now all mailservers A B C can send mails between their domains A B C
Also send and receive to and from external mailservers works.
The YunoHost diagnose is not so happy.
Says 10.10.10.10 should be public IP A
i hope that i dont found other side effects.
sending an email from C to A no longer works
sending from C to B works
/etc/resolv.dnsmasq.conf is unchanged with 10.10.10.1 in the first line
nslookup B shows 10.10.10.20 is okay
nslookup A shows public IP-A is wrong
nslookup A 10.10.10.1 shows 10.10.10.10 is okay
After a restart everything works as expected
It’s a nightmare, i don’t know what’s going on with the name resolution on the yunohost system
