One embodiment provides selectively routing Domain Name System (DNS) request for sub-domains associated with a first network through a tunnel associated with the first network via the interface. DNS requests for sub-domains associated with a second network are selectively routed through a tunnel associated with the second network via the interface. Embodiments include replacing the destination address for DNS requests for sub-domains associated with the second network to match an address of a DNS server associated with the second network. Data representative of DNS requests for sub-domains associated with the second network is stored. Embodiments forward the DNS requests for sub-domains associated with the second network with the address of the DNS server associated with the second network.
