I just inherited a network with 2 Linux servers running Debian as a host OS, with VMWare hosting a number of VMs on both, including the domain controllers and some web sites.
Here is the issue, each server has a VM domain controller, AD and DNS are replicated across both controllers. DHCP on the first controller issues IP addresses for the entire LAN, 192. DHCP on the second controller issues IP addresses, 10.10 to a VLAN.
DNS forwarding on the controller correctly forwards internal requests to a web server hosted on a VM on the second Linux server.
Linux1 Hosts Controller2 Linxu2 Hosts Controller1 and VM web site.
Controller2 has correct DNS Controller1 has replicated DNS
VLAN 10.10 needs to resolve to a VM web site.
DNS lists both domain controllers 1 and 2.
The Forward Lookup Zones are identical except that the Name Servers are switched pointing to the opposite controller.domain
The Host A record points to the same VM
I had tried a Reverse Lookup Zone entry but may have entered it incorrectly. I also tried public DNS on the client but that returns RESOURCE_NOT_FOUND
At one point these changes allowed me to ping the public interface and tracert to same, but it would still not resolve to the web site.
Could someone help with what I think is a fairly simple oversight that I have missed?
