I use a Balance 20 in dual WAN running under firmware 7.10 build 3504. I wish to use my locally connected Raspberry Pi as a DNS server. Specifically I am running the “Pi-Hole” DNS sinkhole to block ads.
The local DNS server works perfectly if each machine on the network is set to use it individually. However if I set the address of the local DNS server in the Balance 20 and use the Balance 20 address for DNS on connected machines there is no address resolution.
I gather from related posts that it is not possible by design to use a local DNS server with a Balance 20 running dual WAN. Is this correct? If not then how can it be accomplished?
The Pi-Hole can act as the network DHCP server if required. This would not however be convenient for my use case.
Thank you for any help you can provide.
