Static Entries
If you do not want to set up your own DNS server but need a static DNS mapping for a few hosts of your network, you can enter these mappings.
Starting with Sophos UTM version 9.1, this feature has moved to the Definitions & Users > Network Definitions tab. DNS mappings are now defined along with the involved hosts.
When you click the Static Entries button, the Definitions & Users > Network Definitions tab opens. Automatically, only hosts with static entry are displayed. Use the drop-down list on top of the list to change the filter settings.
