Patent ID: 7711788

Claim:
A method for enabling access to a data resource, which is held on a file server on a first local area network (LAN), by a client on a second LAN, the method comprising: intercepting a request for the data resource submitted by the client, using a proxy receiver on the second LAN; transmitting a message via a wide area network (WAN) from the proxy receiver to a proxy transmitter on the first LAN, the proxy transmitter being separate from the proxy receiver, requesting the data resource; performing a cross-file-system protocol translation between the proxy transmitter and the proxy receiver; receiving at the proxy receiver a replica of the data resource transmitted over the WAN by the proxy transmitter, wherein the replica was retrieved by the proxy transmitter from the file server over the first LAN in response to the message; and serving the replica of the data resource from the proxy receiver to the client over the second LAN.
