There are many ways to configure name resolution for the fabric domain. One simple way is to set up a conditional forwarder zone in DNS for the fabric. To set up this zone, run the following commands in an elevated Windows PowerShell console on a fabric DNS server. Substitute the names and addresses in the Windows PowerShell syntax below as needed for your environment. Add master servers for the additional HGS nodes.
Add-DnsServerConditionalForwarderZone -Name 'bastion.local' -ReplicationScope "Forest" -MasterServers <IP addresses of HGS server>
