We have an intranet DNS server (system-config-bind on RHEL) serving office A, and a VPN connecting offices A and B. Office A has a server named "dev".
In office A, to access a server "dev" on the local network, the address is 192.168.1.13
In office B, to access a server "dev" over the VPN, the address is 192.168.2.13
My question is this - can I set the DNS server to return a different IP for "dev" based on the subnet of the incoming request?
Example: In office A, BIND returns 192.168.1.13 as the "dev" IP, because the originating request is from the 192.168.1/24 subnet.
In office B, BIND returns 192.168.2.13 as the "dev" IP, because the originating request is from the 192.168.2/24 subnet.
