I am running 2 systems both are ubuntu 10.4 running virtualmin on 2 seprate sumbets. I am usieng both of them for DNS servers one is the master server the other is the slave server. i followed the directions here (https://www.virtualmin.com/documentation/dns/slave-configuration) for setting it up and it wokred just fine
the servers are configured with both ipv4 and ipv6 addresses as exampled
MASTER ns11.bleh.com 192.168.56.73 (yes its natted) 2001:470:1564:1756::73 2001:470:1564:1756:153f:fea4:887a:ffeb
SLAVE ns12.bleh.com 192.168.57.73 (yes its natted) 2001:470:1564:1757::73 2001:470:1564:1757:8766:1fee:56a2:15fd
in the module config for bind on the master server under cluster slave servers i have Default master server IP for remote slave zones set to 2001:470:1564:1756::73
Additional master IP addresses for slave zones set to 2001:470:1564:1756:153f:fea4:887a:ffeb
when i try and add a zone on the master server i get the error Failed to create master zone : Invalid master IP 2001:470:1564:1756::73
my servers are authoritive for my ip6 networks any idea what i am doing wrong.
