A dataframe filter is provided a local area network bridge to monitor the dataframes transmitted on one network to determine those dataframes destined to be communicated to another network by the network bridge. The filter receives and examines the destination address of each dataframe communicated on the one filter and, searching through a database maintained by the filter, determine whether the destination address is located on the second network and, if so, signals the bridge to copy the dataframe to the second network.
