Hi! I've installed and configured my new multiserver setup with 8 servers. Everything working like expected so far, however i have a quick question regarding the nameserver config. Do i simple make ns02 the mirror server of ns01 to achieve a typical master/slave DNS setup? Or is there any further bind config necessary to do so? And in this multiserver setup guide a bug gets mentioned There is currently a bug in ISPConfig that causes DNSSEC signed zones to be signed with different keys if you mirror nameservers.is this still relevant?
