Remote grant of network access

1. A computer-implemented method, comprising:

receiving, at a gateway on a network, a communication including a request for a new network device to join the network;

establishing a connection between the new network device and the gateway, wherein establishing the connection between the new network device and the gateway includes allowing the new network device to connect to a guest entry point of the network;

generating a firewall configured to prevent the new network device from communicating with an existing device on the network, wherein establishing a connection between the new network device and the gateway and generating a firewall configured to prevent the new network device from communicating with an additional device on the network occur at substantially the same time;

transmitting a query, wherein the query includes a request to determine whether the new network device is associated with the network;

receiving a communication including a response to the query indicating that the new network device is associated with the network; and

removing the firewall to allow the new network device to communicate with the existing network device.

2. The method of claim 1 , further comprising: storing a data table including media access control (MAC) addresses associated with network devices on the network, wherein the new network device is associated with a MAC address on the data table.

3. The method of claim 2 , wherein the data table is an address resolution protocol (ARP) table.

4. The method of claim 2 , wherein generating the firewall includes removing the MAC address of the new network device from the data table.

5. The method of claim 2 , wherein removing the firewall includes adding the MAC address of the new network device to the data table.

6. The method of claim 1 , wherein the query is transmitted in response to establishing the connection between the new network device and the gateway.

7. The method of claim 1 , wherein after the query is received, the query is presented on a display so as to allow a response to be entered at the display.

8. The method of claim 1 , further comprising: transmitting a communication, including network credentials, to the new network device so as to allow the new network device to connect to the network.

9. A computing device, comprising:

one or more processors; and

a memory having instructions stored thereon, which when executed by the one or more processors, cause the computing device to perform operations including:

receiving, at a gateway on a network, a communication including a request for a new network device to join the network;

establishing a connection between the new network device and the gateway, wherein establishing the connection between the new network device and the gateway includes allowing the new network device to connect to a guest entry point of the network;

generating a firewall configured to prevent the new network device from communicating with an existing device on the network, wherein establishing a connection between the new network device and the gateway and generating a firewall configured to prevent the new network device from communicating with an additional device on the network occur at substantially the same time;

transmitting a query, wherein the query includes a request to determine whether the new network device is associated with the network;

receiving a communication including a response to the query indicating that the new network device is associated with the network; and

removing the firewall to allow the new network device to communicate with the existing network device.

10. The computing device of claim 9 , further comprising instructions, which when executed by the one or more processors, cause the computing device to perform operations including: storing a data table including media access control (MAC) addresses associated with network devices on the network, wherein the new network device is associated with a MAC address on the data table.

11. The computing device of claim 10 , wherein the data table is an address resolution protocol (ARP) table.

12. The computing device of claim 10 , wherein generating the firewall includes removing the MAC address of the new network device from the ARP table.

13. The computing device of claim 10 , wherein removing the firewall includes adding the MAC address of the new network device to the ARP table.

14. The computing device of claim 9 , wherein the query is transmitted in response to establishing the connection between the new network device and the gateway.

15. The computing device of claim 9 , wherein after the query is received, the query is presented on a display so as to allow a response to be entered at the display.

16. A computer-program product tangibly embodied in a non-transitory machine-readable storage medium, including instructions configured to cause a data processing apparatus to:

receive, at a gateway on a network, a communication including a request for a new network device to join the network;

establish a connection between the new network device and the gateway, wherein establishing the connection between the new network device and the gateway includes allowing the new network device to connect to a guest entry point of the network;

generate a firewall configured to prevent the new network device from communicating with an existing device on the network, wherein establishing a connection between the new network device and the gateway and generating a firewall configured to prevent the new network device from communicating with an additional device on the network occur at substantially the same time;

transmit a query, wherein the query includes a request to determine whether the new network device is associated with the network;

receive a communication including a response to the query indicating that the new network device is associated with the network; and

remove the firewall to allow the new network device to communicate with the existing network device.

17. The computing device of claim 9 , further comprising instructions, which when executed by the one or more processors, cause the computing device to perform operations including: transmitting a communication, including network credentials, to the new network device so as to allow the new network device to connect to the network.

18. The computer-program product of claim 16 , further comprising instructions configured to cause the data processing apparatus to: store a data table including media access control (MAC) addresses associated with network devices on the network, wherein the new network device is associated with a MAC address on the data table.

19. The computer-program product of claim 18 , wherein the data table is an address resolution protocol (ARP) table.

20. The computer-program product of claim 18 , wherein generating the firewall includes removing the MAC address of the new network device from the data table.

21. The computer-program product of claim 18 , wherein removing the firewall includes adding the MAC address of the new network device to the data table.

22. The computer-program product of claim 16 , wherein the query is transmitted in response to establishing the connection between the new network device and the gateway.

23. The computer-program product of claim 16 , wherein after the query is received, the query is presented on a display so as to allow a response to be entered at the display.

24. The computer-program product of claim 16 , further comprising instructions configured to cause the data processing apparatus to: transmit a communication, including network credentials, to the new network device so as to allow the new network device to connect to the network.
