Abstract

Claims (59)

1. A method of establishing a Virtual Private Network (VPN), comprising:

(a) creating a Service Set Identifier (SSID);

(b) creating at least one VPN profile, wherein the at least one VPN profile comprises: information of a Wide Area Network (WAN) interface, wherein the WAN interface is either an Ethernet interface or a cellular modem;

(c) establishing a VPN according to the VPN profile;

(d) associating the SSID with the VPN profile;

(e) when the VPN is established:

(i) enabling the SSID;

(ii) forwarding packets sent to the SSID through the VPN;

(iii) storing the packets sent to the SSID in a first queue and forwarding the packets stored in the first queue to a second queue; wherein the second queue is for storing packets to be sent by the VPN; and

(f) when the VPN is not established, disabling the SSID.

2. The method of claim 1 , wherein the VPN comprises a plurality of tunnels.

3. The method of claim 2 , wherein at least one tunnel of the plurality of tunnels is established using a cellular modem.

4. The method of claim 1 , further comprising providing a user interface for selecting the SSID and selecting the VPN.

5. The method of claim 1 , further comprising retrieving the VPN profile from a remote server.

6. The method of claim 1 , further comprising retrieving information for creating the SSID from a remote server.

7. The method of claim 1 , further comprising before performing step (f) when the VPN is not established, waiting for a time period for confirming the VPN is not established.

8. The method of claim 1 , further comprising: creating an outbound policy to perform step (d).

9. A method of establishing a Virtual Private Network (VPN), comprising:

(a) selecting a Service Set Identifier (SSID);

(b) selecting a VPN;

(c) associating the SSID with the VPN;

(d) when the VPN is established:

(i) enabling the SSID;

(ii) forwarding packets sent to the SSID through the VPN;

(iii) storing the packets sent to the SSID in a first queue and forwarding the packets stored in the first queue to a second queue; wherein the second queue is for storing packets to be sent by the VPN; and

(e) when the VPN is not established, disabling the SSID;

wherein:

the VPN comprises a plurality of tunnels; and

at least one tunnel of the plurality of tunnels is established using a cellular modem.

10. The method of claim 9 , wherein the SSID and the VPN are selected from drop-down lists in a user interface.

11. The method of claim 9 , further comprising retrieving information for creating the SSID and creating the VPN from a remote server.

12. The method of claim 9 , further comprising disabling the SSID when performance of the VPN is not satisfactory.

13. A network device, comprising:

at least one Wide Area Network (WAN) interface;

at least one wireless Local Area Network (LAN) interface;

at least one processing unit;

at least one main memory coupled to the at least one processing unit;

at least one non-transitory computer readable storage medium coupled to the at least one processing unit and storing program instructions configured to cause the at least one processing unit to perform:

(a) creating a Service Set Identifier (SSID);

(b) creating at least one Virtual Private Network (VPN) profile, wherein the at least one VPN profile comprises: information of the WAN interface, wherein the WAN interface is either an Ethernet interface or a cellular modem;

(c) establishing a VPN according to the VPN profile;

(d) associating the SSID with the VPN profile;

(e) when the VPN is established:

(i) enabling the SSID;

(ii) forwarding packets sent to the SSID through the VPN;

(iii) storing the packets sent to the SSID in a first queue and forwarding the packets stored in the first queue to a second queue; wherein the second queue is for storing packets to be sent by the VPN; and

(f) when the VPN is not established, disabling the SSID.

14. The network device of claim 13 , wherein the VPN comprises a plurality of tunnels.

15. The network device of claim 14 , wherein at least one tunnel of the plurality of tunnels is established using a cellular modem.

16. The network device of claim 13 , wherein the at least one non-transitory computer readable storage medium further storing program instructions executable by the at least one processing unit for:

providing a user interface for selecting the SSID and selecting the VPN.

17. The network device of claim 13 , wherein the at least one non-transitory computer readable storage medium further storing program instructions executable by the at least one processing unit for:

retrieving the VPN profile from a remote server.

18. The network device of claim 13 , wherein the at least one non-transitory computer readable storage medium further storing program instructions executable by the at least one processing unit for:

retrieving information for creating the SSID from a remote server.

19. The network device of claim 13 , wherein the at least one non-transitory computer readable storage medium further storing program instructions executable by the at least one processing unit for:

before performing step (f) when the VPN is not established, waiting for a time period for confirming the VPN is not established.

20. The network device of claim 13 , wherein the at least one non-transitory computer readable storage medium further storing program instructions executable by the at least one processing unit for:

creating an outbound policy to perform step (d).
