The feature that Buffalo calls "Privacy Separator" is known to the rest of the world as "AP Isolation" or "Client Isolation", this feature is in DD-WRT and works well.

Block communications between wireless PCs via AirStation.

With a connection setup like that shown in the diagram below, setting this function will prevent computer A and computer B from communicating via AirStation.
(Computer C, which has a cable connection, can still communicate with computers A and B)

Even if you enable the Privacy Separator function, you will not be able to block communications between two PCs if there is even 1 section of cable connection between them.

For example, in the diagram below, even if the Privacy Separator function is enabled, computers C and A (as well as computers C and B) can still communicate. (This is because there is a cable connection between the two AirStations.)

Setup the Privacy Separator function as follows:

1.

Display the AirStation Setup dialog.

Displaying Setup Dialog

2.

Display the Wireless Setup dialog.

Click [LAN Setup] on the left of the dialog.

3.

Enable the Privacy Separator function.

Select the [On] checkbox.

4.

Register the setup contents.

Click [Set] in the dialog mentioned in Step 4.

The message "The following function has been set." appears. Check your settings, then click [Set].

This completes the Privacy Separator setup.
