How to resolve DNS to a second gateway?

[JEdgerly]

Hi,

Fairly straightforward setup (I think), but having trouble implementing.

igb0: LAN (192.168.0.1, Static w/DHCP Server) Home network.
igb1: WAN (47.156.224.x, DHCP from modem) ISP
igb2: LAN 2 (10.106.209.x, DHCP from router) Mesh Network, 'local.mesh'

Typically, I have directly connected to the mesh network with my computer, which allows me DNS resolution to, as an example 'client1234.local.mesh'

Now I have connected igb2 to this mesh as a client, and would like to allow the local.mesh namespace to be resolved by clients on the 192.168.0.x network.

I have tried using the DNS Resolver and a Domain Override for 'local.mesh' and a lookup server address of '10.106.209.241'. No luck. This doesn't seem right anyways, as it seems it should reference the interface or the gateway, not a manually entered ip which is subject to change?

Both the ISP and the mesh are configured as gateways, but I am not sure how to do this...
