Perhaps close all ports then open common ones

20,21, 22 25, 80, 110, 443

You will get a few phone calls and need to open more ports

Otherwise use firewall, its can drop most? p2p traffic built in

53 port number is required for DNS serivce, it is also very important service.
Most popular p2p protocols are recognized by the MirkoTik RouterOS,
you can use '/ip firewall filter add chain=forward action=drop p2p=all-p2p'.
