Simple DNS internal Server setup

Cloud

Hi good day!

1st.) To be specific on my inquiry, i have an internal systems which has an Internal server IP of 192.168.1.X (System), in which staff connected to that using the  server IP, now i would like 

         to change it to a name and not the IP, how can it be done. Sophos UTM

2nd.) Can i make it also to the public IP address or external?, under sophos UTM internal DNS server config? 

 

thank you very much appriciated.

    Ha!

    As you can see from your own screenshot, your production environment uses 8.8.8.8 as its DNS Server. Google-public DNS does not know about your internal DNS settings, you need to change your client's settings to use the internal IP of the Sophos UTM as your one and only DNS-server (just leave the second entry blank).

    And disable IPv6 on the cllents, if using IPv4 only, you don't need two protocols.

    i did try to look at it but im confuse, because that production environment i didnt configure it, they just ask help from me, can u guide me where should i go from that dns 8.8.8.8 because the physical interface and the lan interface i already change and target it to sophos interface, but still nothing happens.

    On the client type type following command:

    ipconfig /all

    and show us the output if you need to. 

    The output should show you the DHCP server (that might be the router). That device is most likely also assigning the DNS server(s). If not, they may be manually set up on the client in the network settings.

    You will need to configure either the clients manually (like I show in the screenshot below) or do it via DHCP settings (automatically assigned)

     

    The IP address for the DNS here ist just an example. You put your Sophos IP here.
