Check the daily data flow and activated ports of each computer in the log under the router; If P2P software is found, it will be blocked directly. Since many P2P software can change ports at present, try to open only the necessary ports and shield all unnecessary ports. There is also closing port printing, and the transmission speed of P2P depends largely on this function.

Only port1-1024 can be opened; 4000-4200 port (Lianzhong game port); 8000-8 100 port (QQ game, that is, port). Then open the corresponding port according to the game played by everyone.

Block port 16 1- 162, so those so-called masters can't disconnect others at will. 135- 139 is also blocked, which is a vulnerability port of WINDOWS.
