My layout is like this:
DC1 - x.x.x.20
DC2 - x.x.x.21
each has a load balanced replicated DHCP scope on it and are on different hardware so i can tolerate failure
PiHole1 - x.x.x.70
PiHole2 - x.x.x.79
as above, different hardware
My lease scope has .70 and .79 as the DNS in the options.
I would like to use conditional fowarding for multiple VLANs and set it up for redundant
VLAN1 - handled by the DC1 and DC2
VLAN10 - handled by firewall x.x.x.254
VLAN20 - same as VLAN10
gonna make up fake scopes here
VLAN1 = 10.20.1.0/24 so the conditional forwarder would be 10.20.1.20 and 10.20.1.21
VLAN10 = 10.20.10.0/24 so 10.20.10.254
VLAN20 = 10.20.20.0/24 so 10.20.20.254
the goal is to get hostnames not just IPs
right now DNS queries go upstream to .20 and .21 only, no others
