Perhaps I can redirected to the documentation link, but since I can't seem to find it online, please assist.

RouterOS v6.27

I want to know how to do the following:

(Unresolved)

Block P2P network traffic (maybe monitor traffic first, and block after?)
-- ????

(Resolved/Figured Out)

Block wireless devices (once detected on the network) by MAC address and/or IP address (I guess this is called MAC Filtering...)
-- Open WinBox
-- Click Wireless button to open the "Wireless Tables"
-- Click the "Interfaces" tab, and double-click on the wireless Interface
-- Click the "Wireless" tab, and deselect the "Default Authenticate" box
-- Click OK
-- Back in the "Wireless Tables", click on the "Access List" tab
-- Click the "+" button
-- Add the MAC Address, and click OK
