Long time reader, first time poster. Love the UTM software full credit to SOPHOS for an amazing firewall implementation.
On my home UTM instance, I have just noticed that i cannot resolve domain names ending .govt.nz . If I disconnect my mobile phone testing device from the SOPHOS controlled WiFi, and connect to mobile data so I'm using the phone companies DNS, the domain names greydc.govt.nz and wcrc.govt.nz resolve fine.
I've tried disabling the DNSSEC validation, configuring the DNS to use only 184.108.40.206 and no forwarders from ISP. I've rebooted the UTM just to be sure, but I still have this issue.
Can anyone help me fix this? : )
