How to set the TP-LINK router WR845n to restrict P2P?

It is difficult for home routers to completely block p2p, but they can still block most p2p traffic if they are not afraid of trouble.

Obviously, bandwidth control is a joke, and dns filtering and ip Internet access control are the correct solutions:

1, dns filtering. This function can't be targeted at ip, so you can't open the banned domain name yourself, so think about it. Add domain name filter, enter keywords such as *.sohu.com, and collect domain names of video websites frequently visited by female compatriots;

2. Of course, dns filtering often fails, so ip access control rules should be set.

The port is sealed. This port is very special. According to personal experience, p2p generally uses 3-4 bit udp port. In order to allow other normal applications to access the Internet, udp and tcp access of 444-7999 and 8006-65535 are generally disabled, while tcp ports of 2 1-443, 4000-4005 and 8000-8005 are generally acceptable.
