DNS Resolution

When creating a new entry (Definitions & Users > Network Definitions) and specifying the Type as Host and Under DNS Settings enter a Hostname and check Reverse DNS, no workstation cannot ping the entry using the specified hostname.
I can ping the IP Address, but despite the Primary DNS and Gateway being set to the UTM address I cannot use the hostname.

I am sure that I am missing something really basic here, which hopefully someone can point out.

(UTM v9.509)

  • Did you configure a FQDN DNS name (like: hostname.domain.tld) or just hostname ?

  • what are your forwarders set to on the UTM? what DNS servers are being handed out via dhcp?  it is an AD domian? If so did you set up a request route?

    Adding the FQDN helped, but upon further investigation I believe that I have some other issues with how I have configured the UTM.
    This may be the catalyst for me building a new firewall configuration from scratch, as my existing system now contains lots of unnecessary remnants from previous configurations.
    Who doesn't need a new project...
