Hi all, After recently losing my beloved Webmin\Virtualmin server thanks to a host losing everything, I decided to setup a slave that would act as a slave dns and backup mail server.
Everything seemed to be going ok but then i noticed that the slave was rejecting some of the updates from the main server.
Having a look through the logs I realised that the master has 2 ip's and that when it updated from one ip it was accepted but rejected from the other.
I followed the instructions here http://www.virtualmin.com/documentation/dns/slave-configuration and did the "Setting the Master IP Address" but only for one. Then i added a space and added the second ip, but that still didnt work either?
I also noticed that when i run a check Virtualmin configuration on the master server I get the following error,
"Default IP address is set to xxx.xxx.xxx.177, but the detected external address is actually xxx.xxx.xxx.165. This is typically the result of being behind a NAT firewall, and should be corrected on the module configuration page."
Could that be the cause of the issue? Errors on Slave log:
backup named[527]: client xxx.xxx.xxx.165#63370: received notify for zone 'domain.com' and backup named[527]: zone domain.com/IN: refused notify from non-master: xxx.xxx.xxx.165#63370
and
backup named[527]: client xxx.xxx.xxx.xxx#45676: query (cache) 'somedomain.com/A/IN' denied
Thanks!
