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.
