A remote access server limits access to a local computer network. The server includes at least one communication port for allowing communication with a remote computer and at least one network port for coupling to a local computer network to allow communication with the local computer network. The server also includes processing electronics which control the communication and network ports. The processing electronics also receive a user identification string from the communication port. The string having been entered by a remote user at a remote computer, and it identifies the remote user. The server uses the string to access a database and determine at least one access filter associated with the string. The access filter is used to prevent the remote computer from communicating with at least one predetermined resource on the local computer network. The database includes a user identification string for each remote user and at least one access filter for each user identification string. The server allows the remote computer to access the local computer network and to communicate on the local computer network, but the remote computer is prevented from communicating with the predetermined resource because of the access filter associated with the remote user.
