I have three networks viz 10.0.0.0/8,172.16.0.0/18 and 126.96.36.199/24. I have a watchguard router,which has Lan IPs, 10.0.0.4,172.16.0.1 and 192.168.0.1 and routing enabled for these networks in this router.Currently I have a DNS server (Bind) in 10.0.0.0 network, and I would like to serve the existing DNS server for other network also. Please explain how to make this setup, do i need to put DNS server for each network ?
Bascially I need to resolve each network machines from other networks.
Hope i explain my setup, if needed i will give further details
