  • Patent number: 10142282
    Abstract: Methods and apparatus for processing DNS request in a gateway with WAN and LAN interfaces. The gateway receives a first DNS request from a host via the LAN interface. The gateway selects DNS servers according to predefined selection policies and selects access networks that are authorized to send new DNS requests. The new DNS requests and the first DNA request have the same content. The gateway transmits the new DNS requests to corresponding DNS sever of the selected access networks through the selected access networks and via the WAN interfaces that are connected to the selected access networks. The gateway then identifies valid DNS responses from DNS responses received from the corresponding DNS server. The gateway selects one of the identified valid DNS responses and generates a first new DNS response with the same content thereof. The gateway sends the first new DNS response to the host.

  • Publication number: 20180262461
    Abstract: A method and system for processing Domain Name Services (DNS) request in a gateway. The gateway receives a DNS request from a host from its local area network. The gateway then selects DNS server(s) and transmits a new DNS request to at least one DNS server(s). DNS server(s) may or may not be accessible through a first tunnel. The contents of the new DNS request are the same as the content of the received DNS request. Further, when the gateway receives a DNS response corresponding to the DNS request, it determines a decision whether to transfer data to the host whose IP address is specified in the DNS response through a second tunnel. The decision may be based on a geographical location of an IP address.
