A method for enabling access to a data resource, which is held on a file server ( 25 ) on a first local area network (LAN) ( 21 a), by a client ( 28 ) on a second LAN ( 21 b). A proxy receiver ( 48 ) on the second LAN ( 21 b) intercepts a request for the data resource submitted by the client ( 28 ) and transmits a message via a wide area network (WAN) ( 29 ) to a proxy transmitter ( 52 ) on the first LAN ( 21 a), requesting the data resource. The proxy transmitter ( 52 ) retrieves a replica of the data resource from the file server ( 25 ) and conveys the replica of the data resource over the WAN ( 29 ) to the proxy receiver ( 48 ), which serves the replica of the data resource from the proxy receiver ( 48 ) to the client ( 28 ) over the second LAN ( 21 b).
