can no longer set 2 ips on also-notify and allow-transfer sections on bind zones

I am issuing again this bug. On issue 42015, I filed 2 bugs. First one was solved. This is the 2nd one which remains.

My slave server has 2 ips (2 isps with load balancing) On master DNS in webmin/services/bind/zone_defaults on Also-notify slaves and allow-transfers I use listed and put the 2 ips of the slave server. This worked as expected for years and on /etc/bind/named.conf.local on the new zone the also-notify and allow-transfer sections contained always 2 ips. However i recently noticed that on newly created servers only 1 ip is used. I think it is the ip of the cluster slave server.

An example

zone "testdom11.gr" {
    type master;
    file "/etc/bind/testdom11.gr.hosts";
    also-notify {
        66.77.88.99;
        //missing 2nd ip here
        };
    notify yes;
    allow-transfer {
        127.0.0.1;
        localnets;
        66.77.88.99;
        //missing 2nd ip here
        };
    };

I have always put the configuration on webmin/services/bind/zone_defaults on Also-notify slaves and allow-transfers and it worked. Did something change recently? Should I put it somewhere else from now on?

Are these domains created via Virtualmin, or are you editing them directly in the BIND DNS Server module?

They are created from Virtualmin

Ok, I see. Where exactly in Virtualmin do you have these two extra slave DNS servers configured?

These are not 2 slave servers. I have one slave server with dual ip (2 isps).

In the master server the slave server is configured in Webmin bind module in cluster slave servers using only 1 ip.

I cannot add the 2nd ip here in cluster slave servers, because it would think it is a 2nd slave server and try to create slave zone twice.

3-4 years ago you have suggested putting these 2 ips of the slave server, on bind module of the master server in webmin/services/bind/zone_defaults on Also-notify slaves and allow-transfers.

This worked for years until recently.

Should i configure it differently?

The best place to enter additional slave IPs is at System Settings -> Server Templates -> Default Settings -> BIND DNS Server, in the "Additional manually configured nameservers" box.

This worked for both master and slave dns!

With this setting i removed also another setting in Webmin i had, because it was no longer needed. In bind module configuration, on cluster slave server Default master server IP for remote slave zones, i specified master ips. Now i set back to default : IP address of hostname.

So it is working now according to my needs. Thank you!
