US 12,120,087 B2 · Domain name system configuration during virtual private network connection

Abstract

Domain name system (DNS) configuration during virtual private network (VPN) connection includes, by a VPN entry server, receiving from a client device, via a VPN tunnel between the entry server and the client device, a first request for first content that identifies a first external source for the first content, receiving, from an operative DNS server configured for the tunnel, an Internet Protocol (IP) address of a first VPN system exit server, in response to determining that the first content is unavailable via the first system exit server, identifying a second DNS server, such that a second VPN system exit server for obtaining the first content is available using the second DNS server, obtaining, from the second system exit server, the first content, wherein the second system exit server obtained the first content from the first external source, and transmitting, to the client device, via the tunnel, the first content.

Dependent claims

A method for domain name system configuration during virtual private network connection, the method comprising:

receiving, by a virtual private network entry server, from a client device, via a virtual private network tunnel between the virtual private network entry server and the client device, a first request for first content, wherein the first request identifies a first external source for the first content, and wherein a first domain name system server is configured as an operative domain name system server for the virtual private network tunnel;
and
transmitting, to the client device, by the virtual private network entry server, via the virtual private network tunnel, the first content, as obtained from a first virtual private network system exit server identified by the virtual private network entry server using a second domain name system server as the operative domain name system server for the virtual private network tunnel, wherein the first virtual private network system exit server obtained the first content from the first external source.

A virtual private network entry server apparatus comprising:

a non-transitory computer-readable storage medium;
and
a processor configured to execute instructions stored in the non-transitory computer- readable storage medium to:
receive, from a virtual private network client device, via a virtual private network tunnel between the virtual private network entry server apparatus and the virtual private network client device, a first request for first content, wherein the first request identifies a first external source for the first content, and wherein a first domain name system server is configured as an operative domain name system server for the virtual private network tunnel;
and
transmit, to the virtual private network client device, via the virtual private network tunnel, the first content, as obtained from a first virtual private network system exit server identified by the virtual private network entry server apparatus using a second domain name system server as the operative domain name system server for the virtual private network tunnel, wherein the first virtual private network system exit server obtained the first content from the first external source.

3 more elements

A non-transitory computer-readable storage medium, comprising executable instructions that, when executed by a processor, perform:

receiving, by a virtual private network entry server, from a client device, via a virtual private network tunnel between the virtual private network entry server and the client device, a first request for first content, wherein the first request identifies a first external source for the first content, and wherein a first domain name system server is configured as an operative domain name system server for the virtual private network tunnel;
and
transmitting, to the client device, by the virtual private network entry server, via the virtual private network tunnel, the first content, as obtained from a first virtual private network system exit server identified by the virtual private network entry server using a second domain name system server as the operative domain name system server for the virtual private network tunnel, wherein the first virtual private network system exit server obtained the first content from the first external source.
