DNS Best Practice

Question

Hello, 
 
 I came across this thread https://community.sophos.com/products/unified-threat-management/f/management-networking-logging-and-reporting/32566/solved-dns-best-practice#pi2353=2 , and tried to adapt my config like you recommend, but i have some understanding problems how to do the config. 
 The actual UTM Hostname under System &ndash; Settings is FW. UTM give DHCP Config to my LAN Clients, DNS Server on Client is the UTM. Point 1 and 2 is done. Point 2. a/ b is not relevant for me. 
 
 And here start my questions how to continue: 
 
 3. Request Routing Domain is then the value for example: 16.172.in-addr.arpa. 
 When the UTM should do Internal DNS Resolution, do I have to create as Target Server and Host Object with Name / IP Address of the UTM ? 
 
 4. Do I have before rename the Hostname of my UTM like fw.domain.local and point to Internal UTM IP as Target Server ? 
 Every Client get via DHCP the Internal IP of the UTM, do I have then also to adapt DHCP Settings -> Edit and add under Domain: domain.local ? 
 
 5. / 6. I don&rsquo;t understand what to do here? 
 
 Thanks a Lot! 
 
 Best Regards 
 Sally

Since you want to achieve something with DNS dont use Dns-hostnames. 
 1.Request route is to resolve local domain. Example printers, clients etc in Active directory 
 For domain.local define the server with its IP. Utm will query that ip for domain.local. 
 2. When you gibe DHCP you have the option to give local domain name 
 3. Hostname in webadmin settings has nothing to do with all this
