Abstract

In one embodiment, a first interface of a switch interconnects with a broadband modem within a wide area network (WAN), while a second interface of the switch interconnects with a WAN interface of a router, where the router provides a gateway between the WAN and a local area network (LAN). Additionally, a web server is provided at the switch, where the web server is reachable to the WAN on the first interface and to the LAN on the second interface. The switch may then inspect traffic received at the first and second interfaces, and determines, based on inspecting, whether to transparently forward the traffic between the first and second interfaces or to redirect the traffic to the web server.

Claims

1. A method, comprising:

interconnecting a first interface of a switch with a broadband modem within a wide area network (WAN);

interconnecting a second interface of the switch with a WAN interface of a router, wherein the router provides a gateway between the WAN and a local area network (LAN);

interconnecting a third interface of the switch with the LAN;

obtaining a private LAN address for the switch;

providing a web server at the switch, the web server reachable to the WAN on the first interface and to the LAN on the second interface;

inspecting traffic received at the first and second interfaces;

determining, based on the inspecting, whether to transparently forward the traffic between the first and second interfaces or to redirect the traffic to the web server;

obtaining one or more files from a remote WAN-based server at the web server; and

providing local access to the one or more files from the web server to a device within the LAN,

wherein the web server is accessible by a user from both inside the LAN and outside the LAN, and

wherein the switch resides logically on a WAN side of the router.

2. The method as in claim 1, wherein inspecting and determining are one of either per-packet or per-session.

3. The method as in claim 1, further comprising:

providing storage associated with the web server accessible to the WAN and the LAN.

4. The method as in claim 3, wherein the storage is selected from one or more of internal storage, local external storage, and WAN-based external storage.

5. The method as in claim 1, further comprising:

attaching a LAN interface of the router to the third interface of the switch, the third interface being logically isolated from the first and second interfaces.

6. The method as in claim 5, further comprising:

allowing for local configuration of one or both of the switch and the web server from within the LAN via the third interface.

7. The method as in claim 5, wherein the third interface is one of either a wired interface or a wireless interface.

8. The method as in claim 1, wherein the remote WAN-based server is a remote web server interconnected between a remote broadband modem and a remote router.

9. The method as in claim 1, wherein the switch is physically collocated with one of either the broadband modem or the router.

10. An apparatus, comprising:

a first interface configured to interconnect with a broadband modem within a wide area network (WAN);

a second interface configured to interconnect with a WAN interface of a router, wherein the router provides a gateway between the WAN and a local area network (LAN);

a third interface configured to interconnect with the LAN;

a web server, the web server reachable to the WAN on the first interface and to the LAN on the second interface; and

a process executed by a processor, and configured to obtain a private LAN address for the switch, inspect traffic received at the first and second interfaces, determine, based on inspecting, whether to transparently forward the traffic between the first and second interfaces or to redirect the traffic to the web server, obtain one or more files from a remote WAN-based server at the web server, and provide local access to the one or more files from the web server to a device within the LAN,

wherein the web server is accessible by a user from both inside the LAN and outside the LAN, and

wherein the apparatus resides logically on a WAN side of the router.

11. The apparatus as in claim 10, wherein the process is configured to inspect and determine on one of either a per-packet or a per-session basis.

12. The apparatus as in claim 10, further comprising:

storage associated with the web server accessible to the WAN and the LAN.

13. The apparatus as in claim 12, wherein the storage is selected from one or more of internal storage, local external storage, and WAN-based external storage.

14. The apparatus as in claim 10, wherein the third interface is attached to a LAN interface of the router, the third interface being logically isolated from the first and second interfaces.

15. The apparatus as in claim 14, wherein the process is configured to allow for local configuration of one or both of the process and the web server from within the LAN via the third interface.

16. The apparatus as in claim 14, wherein the third interface is one of either a wired interface or a wireless interface.

17. The apparatus as in claim 10, wherein the remote WAN-based server is a remote web server interconnected between a remote broadband modem and a remote router.

18. The apparatus as in claim 10, wherein the apparatus further comprises the broadband modem.

19. The apparatus as in claim 10, wherein the apparatus further comprises the router.

20. A system, comprising:

a broadband modem within a wide area network (WAN);

a router configured to provide a gateway between the WAN and a local area network (LAN); and

a switch having a first interface interconnected with the broadband modem, a second interface interconnected with a WAN interface of the router, a web server reachable to the WAN on the first interface and to the LAN on the second interface, a third interface configured to interconnect with the LAN; and

a process stored thereon, the process configured to obtain a private LAN address for the switch, inspect traffic received at the first and second interfaces, determine, based on inspecting, whether to transparently forward the traffic between the first and second interfaces or to redirect the traffic to the web server, obtain one or more files from a remote WAN-based server at the web server, and provide local access to the one or more files from the web server to a device within the LAN,

wherein the web server accessible by a user from both inside the LAN and outside the LAN, and

wherein the switch is logically on a WAN side of the router.
