I've read the best practices with setting up DNS with an existing domain controller. The DC is running DNS and the XG is running DHCP and DNS.
The Sophos XG is 192.168.20.1
Right now I have DHCP assigning the DNS entry as 192.168.20.1 (Sophos XG) and then in the XG I have a DNS Request Route pointing my domain traffic (xxx.local) to the domain controller.
Doing it this way is the only way I can get the PC's to authenticate properly with the domain controller, however now internal host names don't resolve properly.
If I ping PC1, it returns a completely different IP than is assigned to that PC.
If I remove the DNS Request Route option, hostnames resolve properly but now the PC's can't join the domain controller.
