Bridge Packet Control
Bridge packet control is the function that allows an AP to pass only data from those network devices
whose MAC address has been registered for the AP to its clients. Using this function can restrict
communication between user units.
Figure 2.5 shows a sample image of connecting under bridge packet control. The example assumes that,
for bridge packet control, only the MAC address of the router is registered in AP1 and AP2. In this case,
UU1, UU2, and UU3 can exchange data with the external network through the router while they cannot
communicate with one another. When the router is connected to the Internet, UU1, UU2, and UU3 can
access the Internet while they cannot communicate directly with each other.

Figure 2.5. Bridge Packet Control (with MAC address registered)
If the bridge packet control list for the AP contains no entry with the bridge packet control function enabled,
communication is unconditionally permitted between a wired unit and a wireless unit but rejected between
wireless units.
When the bridge packet control list for AP1 and AP2 contains no entry in the above example, UU2 and
UU3 can communicate with each other via AP1 and AP2 while UU1 and UU2 cannot.
Bridge packet control is suitable for a wireless LAN constructed in a public space.
