Sophos UTM9 - Internal DNS Not Working

Hi Guys,


I have Sophos UTM9 setup at home in a small network acting as DHCP and DNS server for the internal network however I cant for the life of me work out how to make internal DNS resolution work.

I followed the best practice guide.

I have added home.local to the DHCP options and verified clients pick this up.

The DHCP IP range is /24, I added in DNS > Request Routing.

I have added static host entries for clients, including setting the DNS hostname field.

DNS forwarders are set to OpenDNS and external DNS resolution is working.


Hopefully I'm missing someone obvious and this is an easy answer?


Here are some outputs from my testing;

DNS request timed out.
    timeout was 2 seconds.
Default Server:  UnKnown

Server:  UnKnown

Name:    shanes-iphone

> shanes-iphone
Server:  UnKnown

*** UnKnown can't find shanes-iphone: Non-existent domain


ping shanes-iphone
Ping request could not find host shanes-iphone. Please check the name and try again.
